The family of a 19-year-old man whose body was pulled from the St. Lawrence River is seeking answers.

Brian Kachur had dinner with his mother on Nov. 14. A graffiti artist, he then went out to do some tagging, and was never seen alive by his family again.

The next morning, his body washed up on shore, a few kilometres from his home in Verdun.

With no suspects, Kachur's family is hoping someone will come forward to help solve the crime.

"My baby brother... I don't know how I'm going to survive without him. I just don't know," said his sister, Laurie Ann Kachur.

The police haven't revealed too much information on the young man's case, other than that they know his death was criminal.

"The autopsy revealed the man had been murdered and there were traces of violence on the body," said Montreal police Const. Daniel Lacoursiere.

The only clue, they say, is an unfinished graffiti tag a few hundred metres from the shoreline.

"Brian always finishes his graffitis. Always," said his sister.

Blood was also found near the scene, but police so far haven't confirmed to whom it belongs.

Kachur's family said the teenager was a regular marijuana smoker. Also, despite being prescribed Ritalin to treat his attention deficit hyperactivity disorder, he refused to take it. He seemed at a crossroad, said Laurie Ann.

"He was trying to find a job he would like. He was sketching, he was trying to find if he wanted to go as a cook, or an artist or as a singer. He didn't know," she said.

For now, Kachur's family simply wants justice.

"Brian's biggest fear was to go to prison and all I want for the murderer is to go to prison and rot there," said Laurie-Ann.

Brian Kachur's family is asking anyone with information to call Info-Crime at 514-393-1133.
