HOUSTON -- A Texas judge on Tuesday dismissed the last remaining charge against two California anti-abortion activists who made undercover videos of themselves trying to buy fetal tissue from Planned Parenthood.District Judge Brock Thomas dismissed the tampering with government records charge against 27-year-old David Daleiden and 63-year-old Sandra Merritt upon the request of the Harris County prosecutor's office.Defense attorneys said the pair never should have been indicted. If they had been convicted of the felony charge, each could have been sentenced to up to 20 years in prison.Prosecutors alleged that Daleiden and Merritt used fake driver's licenses to conceal their identities while dealing with Planned Parenthood. The videos accused Planned Parenthood of illegally selling fetal tissue to researchers for profit.Merritt and Daleiden, who founded a group called the Center for Medical Progress, previously rejected plea deals offering them probation.Texas authorities initially began a grand jury investigation of Planned Parenthood after the undercover videos were released last August.But the grand jury cleared Planned Parenthood of misusing fetal tissue and instead indicted Merritt and Daleiden, who has said he was working undercover as a journalist to expose illegalities in the handling of fetal tissue.We're following this story on Eyewitness News.
