UPDATE: Reports suggest murder was “honor killing”

A Houston man arrested in the murder of his daughter and her girlfriend was “not happy” about the couple’s lesbian relationship, according to a spokesman for the Galveston County Sheriff’s Office.

James Larry Cosby, 46, was arrested Wednesday night and charged with two counts of tampering with evidence in the deaths of his daughter, Britney Cosby, and her girlfriend of two years, Crystal Jackson. Authorities say the charges against James Cosby could be upgraded to capital murder. The bodies of Britney Cosby and Jackson, both 24, were found beside a Dumpster in Port Bolivar, near Galveston, last Friday.

Galveston County sheriff’s Maj. Darrell Isaacks told Lone Star Q on Thursday afternoon that detectives still haven’t pinpointed a motive.

“I know the family was not happy with the girls’ lifestyle that they led, so I don’t know,” Isaacks said. “Apparently, some of the detectives had talked to family members, and they were not very happy with the lifestyle that they lived.”

Isaacks said family members who objected to the relationship included both James Cosby and Jackson’s father, who reportedly is a preacher.

The couple lived with James Cosby in a home owned by Britney Cosby’s elderly grandmother. Isaacks said detectives now believe the murder took place in the home. They had gone there Wednesday night to talk to the grandmother.

“Let’s just say they saw some things,” Isaacks said. “They started seeing things, and they waited for him to get home.”

When James Cosby, who had been at a vigil for the couple, returned home, detectives took him back to Galveston for questioning. He’s now being held on $500,000 bond.

Detectives are still looking for the couple’s 2006 Kia Sorrento and the murder weapons.

“We’re doing lineups for eyewitnesses and stuff like that to see if they can connect the dots,” Isaacks said.

Anyone with information should call the sheriff’s office at 866-248-8477 or Galveston County Crime Stoppers at 409-763-8477.
