there was also more dramatic testimony today and don dahler was at the courthouse. >> reporter: the day began with an up-close look at where dzhokhar tsarnaev's alleged crime spree ended in a bloody bullet-riddled boat. jury members and a heavily guarded defendant were allowed to view the boat where he was found four days after the bombings. back at the courthouse, they heard testimony about the violent gunfight between the tsarnaev brothers and police that led to the elder tsarnaev's death. [gunfire] watertown police officer joseph reynolds described spotting the tsarnaev's green honda followed by the carjacked black mercedes. when he began following them, he stopped. that's when tamerlan came out of his door and started shooting. >> shots fired, shots fired! >> reporter: reynolds said as he returned fire, sergeant john maclellan pulled up in his police cruiser. after a bullet pierced maclellan's windshield, he allowed his vehicle to roll forward toward the tsarnaev

brothers. he used his car door as a shield until he and reynolds could take cover behind a tree. ed davis was boston's police commissioner. >> it's not something that we teach in the police academy but when you run into a life-and-death situation like that, anything is on the table. >> reporter: this photo taken by a neighborhood resident andrew kitzenberg, shows the brothers crouching behind the mercedes. kitzenberg told the court he saw dzhokhar tsarnaev throw a pressure cooker bomb that shook his house. [explosion] he said the brothers also threw smaller pipe bomb, some of which didn't explode. grainy foe shows show officers resting with tamerlan tsarnaev after he ran out of bullets. all of a sudden i could hear an engine rev reynolds testified, the black mercedes was aiming right at us, with the younger brother in the driver's seat. the officers were able to leap out of the way but the mercedes hit and dragged tamerlan tsarnaev 40 feet. when asked who was driving, reynolds pointed to dzhokhar tsarnaev and said, "him."

even with ultimately fatal injuries as well as as being hit by the mercedes, tamerlan tsarnaev continued to fight with officers until they could get handcuffs on him. scott, his young brother eluded capture until he was found in that boat some 18 hours later. >> pelley: don dahler reporting for us from boston tonight. don, thank you very much. now to a very different crime story that has suddenly burst back into the headlines. at the center of it is an eccentric member of a prominent real estate family mark -- man linked to three murders. filmmakers may have accomplished what the police could not do, come up with the evidence to convict him. here's "48 hours" correspondent erin moriarty. >> reporter: it all began in 1982 when 29-year-old kathleen durst disappeared from her home in new york. 18 years later susan berman was found shot dead in her home in los angeles. the following year, the body of morris black was announced in the galveston bay, dismembered

and in plastic bags. all three victims have one connection: man named robert durst, the son of a powerful new york real estate mogul. durst is the main suspect but has never been charged in either the disappearance of his wife kathleen or the execution-style murder of close friend susan berman. he was eventually charged with the murder and dismemberment of his neighbor, morris black. >> is it well-planned and calculated? you bet it was. >> reporter: he told the jury it was self-defense. they believed him. >> we the jury find the defendant, robert durst, not guilty. >> reporter: in early 2011, durst decided to tell his life story to fill maker andrew jarecki. jarecki's six-part documentary "the jinx" has been airing on hbo. the filmmaker confronted evidence that durst may have been susan berman's killer. a letter durst wrote to susan berman that seemed to match the hand writing on an anonymous

letter telling police where to find her body. >> the writing looks similar and the spelling is the same so i can see the conclusion the cops would draw. >> reporter: when the interview was over a shaken durst went to the bathroom still wearing his microphone and could be heard muttering to himself about the interview. >> killed them all, of course. >> reporter: on saturday, the day before the country heard his admissions on television authorities arrested robert durst in new orleans and charged him with the murder of susan berman. today durst's attorney said he's innocent and vowed to fight the charges. >> been durst didn't kill susan berman. he's ready to end all the rumor and speculation and have a trial. >> pelley: so, erin if the tape is what the producers say that it is, would any of this be admissible in court? >> well defense attorneys told me if this goes to trial, they will fight to keep those statements out and, of course, they're going to do what you just said, they're lukely to

raise questions about the recording itself is it what producers say it is? and microphone or not, did robert durst have an expectation of privacy when he went to the restroom? >> pelley: erin moriarty, "48 hours." thank you so much, erin. in ferguson, missouri, the man arrested over the weekend in the shooting of two police officers was in court today to hear the charges against him. they include assault and firing a weapon from a vehicle. 20-year-old jeffrey williams admits firing the shots that wounded the cops last week but he claims the bullets were meant for someone else. in israel, voting begins in just a few hours. prime minister benjamin netanyahu is locked in a tough reelection battle and today he made a last-minute bid for hard-line votes. barry petersen reports from tel aviv. >> reporter: embattled israeli prime minister benjamin netanyahu pledged monday that a palestinian state will not be established if he is reelected. a reversal of his position six

years ago. "we will continue to build and fortify jerusalem," he said, so its division would become impossible. as indicated -- netanyahu's popularity has dropped in recent days, he's appeared to some as increasingly desperate. netanyahu called this snap election three months ago, expecting a break, no-sweat cruise to reelection. instead his main opponent has gained steam and poll numbers for netanyahu are faulterring. ari shavit. >> i would say there is a quiet rebellion against the rule of benjamin netanyahu. >> reporter: critics say netanyahu ignored pocket book issues -- high taxes and real estate prices that tripled in the last decade. shirin and tal vardi are giving up their dream of ever buying an apartment. >> we can't buy a house.

>> reporter: why? >> because we don't... because we need to save so much money for the government and for the country and the taxes are very high. >> i don't want to see bibi anymore. if he will stay, we will go. we can't live here anymore. >> reporter: you'll go? -yes. we'll find somewhere else. >> reporter: with the polls set to open at 7:00 a.m. tomorrow morning scott the best guess that prime minister netanyahu's election is, as one observer put it so helpfully, a toss-up. >> pelley: barry petersen reporting for us tonight from israel. barry, thank you. also unclear is whether a deal can be struck to limit iran's nuclear program. today secretary of state john kerry met with his iranian counterpart. sources tell our state department correspondent margaret brennan that the talks were "a roller coaster." the iranians confronted kerry about the letter that american senate republicans sent to iran last week, warning that any deal

would require congressional approval. margaret asked kerry about that on saturday. >> reporter: so how do you clear the air? are you going to apologize for this let center >> not on your life. i'm not going to apologize for an unconstitutional and un thought-out action for someone in the united states senate for 160 some days. that's just inappropriate. >> pelley: kerry also told correspondent brennan he would be willing to negotiate with syria's dictator, bashar al-assad to remove him from power and end syria's civil war. today assad told iranian tv only syrians can decide his future. the civil war began four years ago in syria as a popular uprising against assad. more than 215,000 have been killed. nearly four million have fled the country. half of them children. yet in the face of unrelenting brutality, heroes have emerged. and clarissa ward went to syria

to meet them. >> reporter: when the bombs rain down on syria, these are the brave volunteers who run in. nicknamed "the white helmet," they claw and saw their way through the rubble to save those buried beneath. here a two-week-old baby trapped under a flattened house for 16 hours is pulled out alive. at a training session in a neighboring country, the volunteers learned how to break through concrete and put out fires. 26-year-old alla from aleppo is one of more than 2,000 syrians who have joined. "everyone loves us in syria," he said. "we deal with all the different groups." do you feel proud of your work? "of course," he said "very." it is dangerous work. the regime has dropped roughly 1,000 bombs on aleppo in the last year alone.

most of them were crudely made barrel bombs packed with explosives and shrapnel. often they'll circle back to drop a second bomb targeting rescue workers. alla told us his friend was killed this way. "he was just 200 yards ahead of us. then suddenly a second barrel bomb landed on his car." what was your feeling in that moment? "i felt desperate," he said. "world leaders are watching the syrian people dying and they do nothing." but the white helmets are undeterred. even in the most hopeless of situation, lives can be saved. to give you an illustration of just how devastating the impact has been of syria's civil war a new report released says that the country's life expectancy has gone down by 20 years scott, from 76 to just 56 since the uprising began. >> pelley: clarissa ward reporting for us on the border

of syria and turkey tonight. clarissa, thank you. rumors were flying when russian president vladimir putin disappeared for ten days. was he ill? did he leave the country? today piewtden reemerged looking fit for a meeting with kyrgyzstan's president. putin seemed to enjoy all the fusss saying "it would be boring without the gossip." now for the race to the white house, before hillary clinton is even officially in it, another controversy is bubbling up. while she was secretary of state, the clinton charitable foundation stopped for the most part taking donations from foreign governments, and it says it will likely do the same again if she runs for president but what about donations from foreign companies linked to their governments? julianna goldman is looking boo this. >> i'm very proud of the work the foundation does. i'm very proud of the hundreds of thousands of people who support the work of the foundation. >> reporter: since its founding, the clinton foundation

has raised at least $42 million from foreign governments and according to an analysis by cbs news, at least $170 million from foreign individuals, organizations and companies covering a range of industries such as banking energy and shipping. >> we're now up to more than $3100 commitments. >> like rilin enterprizes a chinese construction and trade conglomerate that pledged $2 million to the clinton foundation in 2013. it's run by billionaire wang wenliang, a delegate to the chinese parliament and the firm is one of the contractors that built the chinese embassy. >> you want to have the closest security and intelligence connections with the company that's going to build your embassy. >> reporter: jim mann has written several books on china's relationship with the u.s. >> reporter: if the point is that you're not going to take money from foreign governments then his construction company is as close to not just the chinese government, but its ministry of

state security as they could possibly be. >> >> reporter: in a statement, a rilin spokesperson says wang has a long history of generous philanthropic giving and the clinton's organization is one of the many organizations he has donated to. still, there are a long history of complaints about construction workers at various building sites. wenliang was cited twice in new jersey for housing work centers crowded conditions. the company says the charges from 2011 are settled and the 2013 charges were dismissed. campaign finance law pros hint foreign interests from investing in u.s. elections, and scott, the concern is a donor today could be looking for something in return from a future president. >> pelley: thanks, julianna. today the president of vanuatu pleaded for international help. the south pacific island chain was pummeled by a category five cyclone on saturday. at least 24 were killed. 90% of the buildings in the capital were damaged or destroyed. it could take weeks to restore
