HOUSTON — Court documents obtained by KHOU 11 reveal disturbing details about the night a Houston woman went missing over the summer.
A man who police had questioned after Angela Diaz, 22, disappeared has now been charged with promoting prostitution, raising fears Diaz could be a sex trafficking victim.
As we first reported on Saturday, Angela's parents said the Houston Police Department has assigned a human trafficking detective to her case.
She was last seen in southeast Houston on June 30.
“We’re doing everything we can as parents, but we need the help of the community and we need the help of the officers and detectives,” Yesenia Diaz, Angela’s stepmom told us.
Court documents reveal that HPD detectives are investigating a man named Krystopher Karvon Brown. This document lays out a timeline of events leading up to Diaz’s disappearance that trafficking experts know all too well.
On June 4, 2024, undercover detectives contacted Diaz at a hotel for sex. Diaz was detained-and her phone was searched. Detectives found messages dating back to March 2024 indicating Brown had been selling Diaz for sex dates.
When we spoke with Diaz’s family, they said a human trafficking detective may have followed up weeks after Diaz was detained.

“A human trafficking detective, she spoke to my daughter Angela, a week before she got missing,” Edward Diaz, Angela’s father told us.
According to court documents, detectives interviewed Brown after Diaz was reported missing. Detectives say Brown claimed he tracked Diaz using an app called Life 360 on her phone. Late on the night of June 30, he dropped Diaz off at a motel along the Gulf Freeway. Police interviewed a second man, who said he had agreed to meet Diaz to pay for sex. He was the last person to see her before she disappeared.
“This is a traumatic situation for the individual but also the family walking alongside the victim, praying for the victim to get back to [safety],” Kimberly Williams, CEO of the Faith Collaborative group told KHOU.
“Escaping a trafficking situation can be incredibly challenging due to the psychological, as well as physical and financial manipulation that happens,” Williams said.
Houston Police say Brown is not in custody and anyone who knows where he is or has information about Diaz's case should call HPD.
As for Diaz, her stepmom says she is asking the community to pray for Diaz’s safety.
