PORT BOLIVAR, Texas – A Houston man has been indicted on capital murder charges for the deaths of his daughter and her girlfriend.

A Galveston County grand jury indicted James Cosby on Tuesday. Cosby had previously been charged with tampering with evidence in the case.

The bodies of Britney Cosby and Crystal Jackson, both 24, were found in March 2014 outside a store in the 700 block of State Highway 87 on Port Bolivar.

Detectives believe the women were killed somewhere else and dumped at the store.

Investigators later found a lot of blood at Cosby's Houston home.

According to court documents, they searched Cosby s bedroom and found large areas of blood on surfaces throughout.

A criminal complaint filed in court says detectives also noticed a missing window shutter on Cosby s home. They found a shutter matching the missing one covered in blood near where the victim s bodies were found. Detectives say Cosby's thumb print was on the shutter.

Loranda McDonald, Britney Cosby's mother, told KHOU 11 News in 2014 that Cosby was angry that his daughter was gay.

James Cosby is currently being held in the Galveston County Jail on a $300,000 bond.
