Sunday was a difficult Mother’s Day for Angela Palmer, who has spent the last month desperately searching for her missing teenaged son.

Antoine Jarvis, 19, went missing from his home the morning of April 7 -- and hasn't been seen since.

His family is pleading with the public to keep looking for the teen.

“He's a very good soul,” said Palmer. “I, as a mother, I know my son's alive. I know my son's alive. It's just a feeling that I have. I can't explain the feeling, but as a mother, you know.”

A friend last spotted Jarvis on a bus near the Lachapelle Bridge, which spans Rivere des Prairies, around 9:15 a.m.

He hasn't used his phone or bank cards. Jarvis's mother said the disappearance is very out of character for him, because he stays close to home and in touch with his family regularly.

“I am just asking the public. There must be somebody that knows. There must have been somebody that saw something,” she said.

Family members describe the 19-year-old as friendly but shy, and passionate about football.

He also loves music, singing and rapping. He has a tattoo on the right side of his chest that says ‘Arson’ - his stage name.

Jarvis is black, 6 foot four (1.93 metres) and weighs around 200 pounds (90 kgs).

“Because of the time that's elapsed, he should be bearded up now and his hair should maybe be in a two-inch afro,” said his mother.

He was last seen wearing a white winter coat.

Jarvis had recently struggled with mental health issues. Days before he went missing he'd been given medication that made him feel confused and dizzy.

“I have seen and heard these things happen at a distance, but I just fully realized when it came home now to my family,” said the young man’s grandfather, Charles Palmer.

“Where is he sleeping? What is he eating? Where is Antoine? It's very, very difficult,” said his grandmother Maud Palmer.

Laval police confirm Jarvis's disappearance continues to be investigated by the major crimes unit, adding that there have been no major developments. They confirm they have searched the waters around the Lachappelle Bridge.

The Missing Children's Network has been assisting the family with their search.

“Often what happens is the fact that we don't talk about a missing loved one anymore, the public is under the impression that the person in question has been found and in Antoine's case, this is not the situation,” said spokesperson Pina Arcamone.

There was a 50-person search for Jarvis on April 17, which turned up empty. Jarvis's mother continues to search for him every day, hoping for his safe return.

“No matter what in life that you're going through, no matter how difficult you think a situation is. Antoine just come home,” she pleaded.

Anyone with information is urged to call Laval police at 450-662-INFO (4636) or the Missing Children's Network at 1-888-692-4673.
