HOUSTON -- A person of interest in the case of two female roommates found dead in southwest Houston surrendered to police Wednesday morning, police told KPRC Local 2.

Detectives with the Houston Police Department said Derrick White, 35, is a person of interest in the deaths of his two female roommates on Monday. He was booked into the police department's jail at about 3 a.m. but has not yet been charged.

White told police he was urged by a relative to turn himself into police.

One of the women was found in a storage closet at an apartment complex on United Drive near West Sam Houston Parkway South, where he and the victims lived. The other woman was found in the trunk of a car towed to a storage lot on Ronda Lane near the Southwest Freeway.

Investigators have not commented on how the women were killed.

Arianna Mingo's family believes she was the woman found dead in the trunk of the car. Relatives said the 35-year-old woman was White's girlfriend.

"It's hard on the kids because this is her baby right here, standing on the side of me, and she keeps asking for her mother," Mingo's mother, Theresa Daniels, said.

"I'm not happy with that. She's always been in my heart. She was like a friend to me," Mingo's daughter, Arielle Mingo, said.

The other victim's name has not yet been released.

White has been charged with 10 prior offenses since 1989, including an aggravated assault-murder charge in 1997. That charge was later dropped.
