them, they did an hour search. 50 feet. 50 feet from where his truck was found, that's not going to take them that long. >> when we left scene, we were confident there was nobody there. in hindsight, did it work out the way it was supposed to work out, not at all? but given the circumstances that's the way it happened. it's unfortunate. >> priscilla says she's now making it her mission to get answers. >> i want to know what happened to my brother, and i'm not going to stop until michael can wake up. he's on life support right new and it hurts me, kills me. >> reporter: priscilla says she

to study the remains found in that potter's field on the campus of san jes's valley medical center. the cemetery was used at the turn of the century. it was uncovered by construction crews earlier this week. nbc bay area's kimberly terry broke the story for us on tuesday. she is live in san jose with the new details. what now really? >> reporter: well, archaeologists are just waiting for their turn, hoping that the site will be opened to them. some county officials claim they didn't even know that the cemetery existed at valley medical center until the construction crews started digging and accidentally unearthed some of the pine coffins. now archaeologists say this is a major opportunity to do research on the medical and cultural history of the people buried there. >> well, every large city and town probably had a potter's field, you know, and they probably had the same history that they are forgotten. >> reporter: archaeologists say many buried in these types of cemeteries at the turn of the century did not have family who could afford a burial or they could not be identified to even let next of kin know. they say while it's highly unlikely ancestors will now come forward to claim the bodies, it's not out of the question. >> whiskers were there, the clothing there, the button still there. you can see the beard. >> reporter: this averageologist worked on the potter's field discovered years ago. he says there still might be identifying clothing or articles in the coffins at valley medical. >> they should be studied, but i recommend that they be treated not only statistically as a group but also they should be described and treated as individuals, and it maintains their humanity. >> reporter: archaeologists are hoping santa clara county takes the time to do a comprehensive analysis of the remains. >> i think that it's an opportunity to -- to tell a story for each body. can you learn a lot of things about the health, the status of their health when they died but also what happened to them during their lives. >> reporter: but a dig like this won't come cheap. >> money is the root of everything, and, you know, doing a proper archaeological dig, particularly with human remains in large numbers, is by no means an inexpensive undertaking. >> reporter: some archaeologists estimate it could run into hundreds of thousands of dollars for this type of research but say it's worth it. they say the people who are buried at potter's graves were largely forgotten, and they don't want to see history repeat itself. right now the county is poised to ask a court to allow them to remove 100 of the pine boxes and the remains that are in their immediate path of construction. live in san jose, kimberly terry, nbc "bay area news." >> fascinating story.

16-year-old redwood city student was dropped from sequoia high school's honors program after teachers found he copied another student's homework. the boy's father, who said he was worried about the impact it would have on his son's college career, claimed the punishment didn't properly fit the crime, and he sued the district and the school. but now a judge has sided with the district and refused to reinstate the student in his honors class ruling the student wasn't sufficiently harmed and probably couldn't win the case in a trial. now a growing controversy over a tax initiative to save the schools from the budget ax. earlier this week governor brown made a pitch to voters saying a yes vote on the initiative for temporary taxes in the neve election is the only way to spear schools from trigger cuts. >> and the fact is that if you vote for the initiative that i'm proposing, you will avoid millions of dollars of cuts. if that is no, there will be $5.5 billion in cuts to the schools of california, no and, ifs or b.u.s. >> can the governor bluffing? the in-depth analysis from a non-partisan source. you heard a lot of people say that jerry brown is really twisting arms. is he bluffing? >> i don't think he's bluffing, but what he's doing is use the fact that both callians say they would support a tax increase for schools. most californians say they are most opposed to cutting spending for schools. >> you can hear more this sunday at 9:30 on "class action." hope you join us. where is our chief meteorologist jeff ranieri? >> where is jeff ranieri? >> you know what?

>> and a machine anybody can make. >> kind of one demo of hundreds of different demos that will be out here where people can actually touch and create themselves and also learn about what's going on. now, where did you get this idea from, real quick? >> well, you know, we saw one of the machines, and so we joined the bay area group and learned more about making the machines, and this is one that

as it dellved into california's new revolutionary cap-and-trade program. one lead investigator spent four months researching this new law and he now joins us with a preview of his special report. >> reporter: california's new cap-and-tray law is being watched around the nation and around the world. it's revolutionary, a first of its kind, and if it works, it could set the standard for economic and political systems around the world in the future that will all reduce greenhouse gases. but we discovered, even before california's law is really even gotten started, it's coming under fire. critics say it's gamed and won't really result in a cleaner environment. under california's new cap-and-trade law, companies that pollute will be able to mitigate up to 8% of what they put into the air by purchasing what's called carbon offset credits. >> it's a tough road to hoe to get a ton of offset credits. >> reporter: stanley young serves as communications director for the california air resources board, the state agency that will oversee this revolutionary new cap-and-trade law. >> we want to make sure that every ton that we get from an offset is as rigorous, strict and permanent as the ton we get from reducing at the industrial facility. >> reporter: and those carbon offset techniques range from getting rid of old chemical fridge rants and capturing methane from dairyarm manure, to planting trees, both in the city and reforesting the wilderness. it is that practice, getting carbon offsets for planting new trees in the forest, where we encountered questions about the current rules and whether they truly reduce greenhouse gases. >> especially when they initially do all this, they dump all this carbon into the atmosphere. >> what that is -- >> reporter: ron and bruce castle and susan robinson are all members of the environmental group ebbot's path forest watch and concerned of the new rules. i think of it as gaming the system. >> logging companies should not be allowed to be subsidized for this kind of practice. >> reporter: companies that harvest timber claim they are reducing greenhouse gas emissions an changing their business practices as they demonstrate in their graph of one of their 100-year plans. >> we are withholding harvest that we could otherwise have done. >> in order to get the carbon offset. >> in order to maintain the carbon offsets that we've sold. coming up tonight at 11:00, we'll take you behind the scenes, and as you see deep into the forest where we will examine up close these questions and whether the system will result in a decrease in greenhouse gases or whether the system is susceptible to being gamed. we'll see you tonight at 11:00 p.m. see you then. now a follow-up to another investigation regarding fan violence. today in

trow sisters have filed a civil lawsuit against the city of antioch, including the police department, also named as defendants are contra costa county, child protective services and a local church. the smiling faces of the girls in this photo do not reflect what was happening behind the closed doors of this antioch home. for two decades the six dutroux girls were sexually molested and raped by their four. bruce dutro is serving life in prison for a long list of sex crimes and his wife priscilla is serving 15 years for facilitating the abuse. >> it is sickening to know that that is occurring. >> reporter: this attorney represents the dutro's four biological daughters and two nieces under the dutro's legal guardianship. the lawsuit claims in 1995 oldest daughter went to a pastor at cavalry open bible church in antioch and told him about the abuse. >> instead of reporting this abuse they directly called the molester, the deft, the father, and told him, and that's how this injustice began. >> reporter: he says the abuse continued even after the girl's father became a registered sex offender in 1995 and was ordered to stay away from the family home for six months. >> his wife during the six months would shutth girls, one by one every night, over to his apartment while he's on probation as a sex offender, and he would sexually molest each one of the girls. >> reporter:
