A Missouri teen who vanished nearly two months ago may have consumed drugs that were "laced" prior to his disappearance, according to his grandmother.

T'Montez Hurt, a 19-year-old student at Missouri Western University, last spoke to his grandmother, Tecona Donald-Sullivan, on Feb. 1, during what she described as a distressing phone call at the home of a woman he had recently met.

"He just didn't sound like himself. He was rambling, not making sense. My grandson smokes marijuana," she told KSDK-TV. "I kept on hearing him ask the girl, 'What did you give me? What did you lace me with?' and I asked him who she was, and he just said, 'I don't know granny.'"

"I then sent him to a hospital because he was not himself," Donald-Sullivan recalled of her last conversation with her grandson.

Hurt reportedly went to the hospital, but was discharged a short time later. He was last captured on surveillance video trying to get inside a closed Kansas City Greyhound Bus Station.

"He hasn't been seen since," said Donald-Sullivan. "When I talked to the police, they told me traffic cameras in that area also caught him on video walking many blocks down the street. The police never let me see that traffic video because they said it was part of their investigation."

Now, nearly two months on, police are asking for the public's help in locating the missing college student.

"That's all I wanted in the beginning was to get him out there because Kansas City is very big," she said. "I don't know what it took for them to ask for the public's help, but I'm just glad they finally did, and I say thank you."

T'Montez is described as a Black male,approximately 6-foot-1 and 160 pounds, with black and red hair, and brown eyes, according to police. He was last seen wearing a royal blue Price Chopper polo & green sweatpants. He has a tattoo on his right arm. 

Anyone with information on his whereabouts is urged to contact Kansas City police at 816-234-5043.
