Arrest in slayings case

Galveston County Sheriff Henry Trochesset answers questions Thursday during a press conference after he announced that James Larry Cosby, 46, below left, was arrested and charged with evidence tampering in the deaths of his daughter, Britney Cosby, and her partner Crystal Jackson, bottom left, whose bodies were discovered next to a Dumpster on the Bolivar Peninsula last week. 


PORT BOLIVAR — Sheriff’s deputies Thursday arrested the father of one of the two women found dead outside a Port Bolivar convenience store last week.

Houston resident James Larry Cosby, 46, was charged with two counts of tampering with or fabricating physical evidence with intent to impair a human corpse in connection with the deaths of his daughter, Britney Cosby, and Crystal Jackson, both 24. 

Cosby is being held in the Galveston County Jail on bonds totaling $500,000.

The investigation into the double homicide is ongoing, and the charges against James Larry Cosby may be upgraded to capital murder, Sheriff Henry Trochessett said.

Both women were killed sometime between March 6 and 7:45 a.m. March 7, when a beer deliveryman found their bodies near a metal garbage container outside a Port Bolivar convenience store, about a mile from the Galveston-Bolivar Ferry, according to the sheriff’s office. 

Britney Cosby died of blunt force trauma. Jackson was shot to death. Officials are awaiting toxicology reports on the bodies, Trochessett said.

Authorities have not confirmed a motive in the killings. Detectives have said the two women were in a relationship, but it’s unclear whether the double homicide would be considered a hate crime.

Some of the slain women’s relatives, including James Larry Cosby, attended a vigil near Cosby’s home in the Sunnyside subdivision of Houston on Wednesday. 

While interviewing Cosby at his home Wednesday evening after the vigil, detectives saw “blood and other evidence” that led them to suspect he may have been involved in his daughter’s death, Trochessett said.

The sheriff’s office is treating Cosby’s home as a “secondary crime scene,” and it may be where the two women were killed before their bodies were driven to Port Bolivar and dropped off, Trochessett said. 

Investigators obtained a warrant to search the home, and Cosby was brought to Galveston for further questioning, he said.

A judge signed the warrants for Cosby’s arrest at about 4 a.m. Thursday morning, Trochessett said.

Cosby’s criminal record includes two convictions for unlawfully carrying a weapon, according to Harris County court records.

In 1994, Cosby was sentenced to 10 years in prison after being convicted of sexually assaulting a 22-year-old woman, and in 2011, he was sentenced to two years for failing to register as a sex offender, according to court records. 

Cosby was released from prison in October, Trochessett said. 

On Sunday, the sheriff’s office released a composite sketch of a “person of interest” in the investigation, a man who authorities said was last seen with the two slain women.

Cosby’s appearance bears some similarities to the man depicted in the sketch, Trochessett said.

“He could have altered some of his facial features, as far as hair and things like that,” Trochesset said.

Deputies are still searching for Britney Cosby’s vehicle, a silver 2006 Kia Sorento with gray trim and paper plates.

It’s likely that James Larry Cosby had access to his daughter’s vehicle, but he has so far been uncooperative with investigators, Trochessett said.

Trochessett said the families of Britney Cosby and Jackson were probably “shocked” by James Larry Cosby’s arrest.

Britney Cosby’s grandmother, Patricia Nixon, said at a vigil in Port Bolivar on Tuesday that her granddaughter was well-liked by everyone she met and had hoped to enroll in college, possibly to study nursing.

John Cooks, Jackson’s uncle, said Tuesday that his niece was close with her family, particularly her 5-year-old daughter.

That's just heartbreaking.

This story is tragic enough. I really hope it doesn't turn out that he killed his own daughter and her companion. [sad]


Well I don't give compliments easy or often, but what the heck, congratulations to Sheriff Trochessett, his investigators, and officers for cracking this case WIDE open!! Well done, Well done,...I wish I could give all yall a raise!!!

Miss Priss

Yes but the credit really goes to Barry Cook and his team of detectives AND also Quanell X whether you like him or not. I believe he is the one who go through this guy.

From his background, father doesn't appear to have been any good positive role model or influence on the daughter. So sad that she seemingly turned out to be a good person, found a companion to share her life. Father could have been envious of daughter.

It will be interesting to see through court proceedingswhy father (or whoever did this crime and transported bodies) chose Bolivar as a depository location for the deceased.

Sorry, it would be interesting to find out why a father would kill his own daughter. Who really cares a flying leap of where the body is deposited? This is one sick a$$ individual.

The murder may stem from the father's Muslim religion. "In Islam homosexuality is forbidden. It is forbidden. I learned today that Larry was a practicing Muslim," said Quanell X. Quannel X claims he found writings about homosexuality on Cosby's Koran indicating he may have had an issue with his daughters sexual orientation.

Very interesting. And, as I indicated in another post, Quannel might very well be in a quandry. Because of Quannel's muslim beliefs, he likely shares with the father a "forbidden" view toward homosexuality. His current representation of the deceased daughter might be in a conflict of interest with his core beliefs.

A perfect example of how a strict adherence to a belief system that "shuts out" otherwise good people can create inner turmoil to the strict "believer". Bottom line is that it really isn't prudent to condemn one for a "lifestyle" (that otherwise is not harmful to others), just because you don't approve of it. Much deeper is one's character, in regard to treating others kindly and serving society in a positive capacity. Sounds like daddy could very well have been an advocate of "straight lifestyle" in relation to her daughter, yet he never looked to himself in regard to his abusive behavior toward women. Sounds very hypocritical and twisted.

Au contraire. The investigative component regarding choice of despository of body can be integral in determining the leading causes of the two young women's murders.

That is, could the daughter have said to the father that they were going to Galveston to perhaps cement their relationship in a marriage ceremony? Or, was there simply a psychological reason within the brain function of the father (alleged perpetrator) where he felt that going over the causeway and moving the body in a remote area would somehow diminish the act that he committed?

Along with all of this, it is interesting that we aren't hearing anymore from Quannel X. I believe, more than ever, that his Muslim belief and its opposition to homosexuality has caused Quannel to recuse himself from further publicity in this case. These are, I would argue, indeed the kinds of things the public wants to hear more of.
