Texas man accused of killing, dismembering missing Houston woman. Police still hunting for her remains.

A Texas man is accused of killing his ex-wife, who is missing, and police fear her body was dismembered, authorities said.

Sean Dacko Preston, 47, was charged with murdering his ex-wife, Keysha Preston, 41, at a Houston-area motel around Nov. 24. Houston police say he may have dismembered her remains.

On Nov. 29, family members told authorities Keysha Preston had been missing since Nov. 24, according to Houston police. Investigators determined her disappearance was suspicious and started an investigation.

Police believe Preston stuffed his ex-wife’s body in duffel bags after killing her and possibly used acid to destroy her remains and evidence, according to court documents.

Police reportedly obtained surveillance footage from the motel where he was staying, which allegedly showed him and a woman entering his motel room together on Nov. 24. Hours later, the footage is said to show Sean Preston exiting the room carrying “what appears to be a heavy bags to his car,” which he “had trouble getting the suitcase or duffel bag on wheels down the stairs and had to use both hands to lift it into the trunk.”

"(Keysha) never exited," prosecutor Janna Oswald told ABC 13 News. "We see (Sean) go in numerous times with duffle bags and other ways to carry things. He does carry things, things that looked heavy, and (Keysha) was never seen."

Keysha’s mother, Sheryl Blakes, told Click2Houston.com, she believes Sean Preston lured the mother of his three children to the motel with money.

Blakes alleged Sean Preston also physically abused Keysha Preston in the past. Court documents showed Sean Preston was charged at least three times for assaulting his ex-wife.

“I would tell her all the time ‘Leave that man alone,’” Blakes said.

Nine days before her disappearance, Keysaha Preston accused her ex of inappropriately touching a child in her family, according to documents obtained by The Houston Chronicle.

Preston was arrested on Dec. 15 and was charged with sexual assault and murder.

He remains held in Harris County Jail, and his bond has been set at $2 million for the murder charge and $250,000 for the sexual assault charge, according to records from the Harris County Sheriff’s Department.
