Harris County investigators have named two suspects in the murder of a Houston nurse and the disappearance of a University of Houston student.

Brandon Lyons is charged with capital murder in the death of 44-year-old Glenser Soliman.

HCSO investigators say Lyons and his cousin, Jerrett Jamal Allen, are also suspects in the disappearance of 26-year-old An Nguyen.

Investigators say there are similarities in both cases.

"Both of them were Asian males, both of them were possibly using social media chat sites, and both of their vehicles were abandoned in similar areas," said HCSO Senior Deputy Investigator Mike Ritchie.

Detectives believe the suspects used a social media dating app to lure the victims.

Soliman, a nurse at St. Luke’s Hospital, vanished without a trace back on February 16. His body was found 11 days later by a man walking his dog in the 2800 block of Hirschfield Road. He had been beaten and strangled, according to court documents.

Soliman's car was later found in the Spring apartment complex where Lyons and Allen live, according to investigators.

Lyons, 18, was charged with auto theft in April. Investigators say they eventually found enough evidence to charge him with capital murder.

Nguyen was last seen on March 31 in northwest Harris County. His 2016 four-door Jeep Renegade was found abandoned a couple of weeks later near where the suspects live. But there was no sign of the UH student.

Nguyen also had a degree in nursing, but his family said he enrolled in the University of Houston’s Hotel and Restaurant Management program because it seemed more fun.

His family has given up hope that he will be found alive.

"This is unlike him, he's very close to his family," Ritchie said. "A lot of them live together and they're very close, they're tight-knit, they talk often."

Allen is charged with unauthorized use of Nguyen's credit cards but he is not in custody. He was last seen in El Paso.

Crime Stoppers will pay up to $5,000 for information leading to the charging and/or arrest of Allen. Information may be reported by calling 713-222-TIPS (8477) or submitted online at www.crime-stoppers.org.
