Galveston county investigators arrested James Larry Cosby, 46, Thursday morning. Investigators say they believe both women were murdered at his home.
Cosby is now in jail, charged with two counts of tampering with evidence after the double murder of his daughter, Britney Cosby, and her girlfriend, Crystal Jackson.
Galveston County investigators arrested James Cosby after searching the south Houston-area home he shared with the young couple.
We've been following this double murder case since the bodies of both 24-year-old victims were found by a dumpster behind a grocery store on Bolivar Peninsula last Friday.
James Cosby was among the large group of family and friends who gathered to remember the victims during a candlelight vigil Wednesday night. Investigators tell me it was after that vigil, they interrogated him.
"His house was a secondary crime scene, from the evidence that we saw when we went to interview him and we did recover certain parts of evidence that are here at our sheriff's office now to be sent to the lab," said Galveston County Sheriff Henry Trochesset.
Right now, detectives are still searching for the silver 2006 Kia Sorrento that belonged to the victims. That truck is still missing.
We did some checking into the accused man's criminal history. Investigators say Cosby was just released from prison in October. And he's a convicted sex offender whose past arrests include several assault and weapons charges. For now, Cosby remains in jail on a $500,000 bond.
Investigators say it's possible the charges he's facing could be upgraded to capital murder.
