A San Diego father arrived in Houston looking for answers to the disappearance of his 24-year-old daughter, Felicia Johnson.

Johnson was last seen getting into an unknown male’s car after applying for a job at the Cover Girls strip club, CBS 8 reports. While Felicia’s bloody cellphone was later located, the young woman hasn’t been seen or heard from since April 15.

“If somebody knows something, say something,” Felicia’s father Kevin Johnson said. “It’s a community of silence out here and secrets.”

Felicia was in Houston celebrating her birthday and wanted to make some extra cash, so she applied for a job at Cover Girls. Authorities say Felicia was waiting for an Uber at around 1:30 a.m., but her family believes she got into another vehicle.

Felicia’s phone was found covered in blood 12 hours after she disappeared. Texas EquuSearch spent three days searching the area where Felicia’s phone was found but didn’t locate any signs of her disappearance.

“The phone was like someone threw it out the window, and it had specks of blood that I think came from her finger during the struggle,” Kevin said.

Felicia’s father, and Albert Flores, a National Investigator for The New Black Panther Nation, believe Felicia might now be a victim of sex trafficking.

“We are the national hub of sex trafficking,” Flores said.

The Houston Police Department is investigating the case and offered a $5,000 reward for any information, KHOU reports.

“I don’t know the exact circumstances, but somebody is holding her against her will,” Kevin said.

An attorney for Cover Girls said the club is cooperating with authorities and turning over surveillance video related to the case. Felicia’s father continues to beg the public for any information related to her disappearance.

“Find it in your heart to have some compassion for human life,” Kevin said. “If she’s watching this that I’m not gonna rest until I find you or find out what happened to you.”
