There is a sad update in the murder investigation of a lesbian couple found dead in Texas this month. 24-year-olds Britney Cosby and Crystal Jackson were identified last Friday and now Cosby’s father, James Cosby, has been arrested, charged with tampering with evidence and is being held on $500,000 bail in the Galveston County jail. The Houston Chronicle reports that Cosby didn’t approve of his daughter’s sexuality or relationship with Jackson. When questioned, he also couldn’t tell police why his prints were found at the murder scene of his daughter and her girlfriend, along with the bloody rug found at his home in Houston.
