A missing 21-year-old University of Houston student and son of a Michigan congressman has been found safe.

The mother of Carl Conyers has confirmed that her son is alive and safe and back with her on Friday morning.

“I just want to get him home, get him checked out, and get his mental health observed. I just want to put this behind our families right now,” said Conyers’ mother, Monica.

Mrs. Conyers got the call from UH Police overnight. He was found at his apartment complex around 1 a.m. Friday after UH Police received a tip from Conyers’ girlfriend who said they should stop by his apartment near campus along Southmore Boulevard.

When police arrived at the apartment complex, they found Conyers in his unit. He was taken to UHPD headquarters where he was questioned by police and reunited with his mother.

Conyers was then taken to the Houston Police Department where investigators questioned him further before he was released back to his mother.

She says her son needed a shower and hadn’t eaten and wasn’t feeling well. He's now resting.

“He doesn’t even know where he was. He doesn’t know. He doesn’t know, so we’re just trying to sort it all out right now, give him a little space, and make him feel better,” Monica Conyers said.

When asked by KHOU 11 News if investigators were working for anyone linked to the disappearance of Carl Conyers, Houston Police would only say, following their interview of Conyers, “circumstances surrounding his disappearance remain under investigation.”

Conyers’ mother said she noticed that her son was walking with a limp, but is not sure where it came from.

“I know he didn’t leave on his own. That much I do know,” Monica Conyers said.

Carl Conyers is the son of U.S. Rep. John Conyers, D-Michigan.

Conyers was reported missing after he was last seen Tuesday. His roommates were worried because his car and wallet and phone were left at the apartment. He also didn’t show up for work. They added that he seemed stressed and said he had a crazy day.

"He was cooking. I greeted him. I noticed he was hiding his face a little bit," said Chat Ball, a roommate. "I didn't think much of it, just because of the fact that school can be hard on a person. Stress is very serious."

His girlfriend panicked when she received a cryptic tweet telling her to meet him at UH, but Carl never showed.

There was an all-out search for Conyers Thursday. Monica Conyers flew to Houston from Michigan Thursday afternoon to help with the search.

Conyers' Twitter account indicates he's the president of the Black Business Association at UH and is the marketing director for the Uncommon Colors organization. He's in the class of 2018.

A spokesperson for Rep. John Conyers sent a statement Friday morning saying, “Rep. Conyers has been in touch with his family and is happy his son is safe and uninjured."
