rainfall for january, february and march, 24% of what we need or what is average in santa rosa. 13% of what is average in san francisco. 30% for livermore. and only 23% for san jose. so not only did the drought stick this winter, it got worse even after that record setting december. we need more rainfall. and simply put it is too late in the season to end this drought because now the rainy season is wrapping up. out here live, the lafayette reservoir, one of the reservoirs that is the most full of any in the bay area. if every reservoir looked like this we won't have a problem. but there is a problem. even though there's rain in the forecast, it's a problem that will be with us for months. we'll talk more about the chances of rain which may impact your holiday weekend coming up in a few minutes. it is a problem because one northern california community is already in a dire situation. people having to cut back water use by 50% are on the verge of running out. that's coming up tonight at 6:00. a very strange crime on the

>> reporter: this afternoon, i spoke to the suspect's attorney. he said she has not yet entered a plea in the case although she did make statements to officers last year, elizabeth. she said that when she was asked about whether or not she had done this, she said, quote, i just grabbed whatever was around even tap water, end quote. so this will be moving ahead in court here in santa clara county. >> it is curious, len, how she was able to access this very, um, harmful ingredient. would you think something that was so dangerous would be under lock and key? >> reporter: in the research lab this is a very common thing. people have it on their desks or work spaces in that type of a research facility. it is a very common thing that people have. and it's so common that some of her victims may have not even noticed it because they became so accustomed to the smell of it that they couldn't tell when they drank it. others who might have been newer around the lab noticed something was wrong right away. >> wow. very bizarre. all right, len, thank you.

purpose of measure d. now, burgermeister says it will get the $455 it's collected so far to the city and stresses this was an honest mistake. the city has plans for an outreach program to clarify the measure. and remember, if you have a consumer problem, story idea, give us a call 888-5-helps-u. >> they are also offering a 22- cent discount for the rest of the month on soda to make up for it. >> thank you. a double-digit sales tax took effect today in five east bay cities. it's 10% in hayward, union city, albany, el cerrito. voters in five cities approved the increases last year. the extra revenue could amount to $10 million a year in hayward alone. money the city can use to beef up the police force and repair the roads. we all know it takes a pretty penny to buy a home in san francisco and now it is confirmed. it takes nearly a million dollars to buy what's considered an average home in the city. one real estate firm says
