The family and friends of a young Halifax man who was killed last month are speaking out against violence in the city.

Almost a month has passed since 26-year-old Kaylin Diggs was punched in the head during a fight after leaving a downtown bar.

Diggs was walking down Argyle Street with a friend on Aug. 11 when the pair was approached by a group of men. A fight broke out and Diggs was dealt a fatal blow to the head.

His cousin, Quentrel Provo, ran into Diggs downtown shortly before his death.

“We had such a really good talk,” says Provo. “We were talking about his mother just getting married and how happy he was about that and he told me I had to sing at his wedding.”

“You know, for an hour later to lose him…words can’t explain how much I cherish that moment I had with him.”

Diggs grew up in East Preston and was studying to be an electrician. His girlfriend, 25-year-old Natasha Roche, says he was happy and looking forward to the future.

“We were going to buy a house…supposed to go away in a week from now to Lunenburg…going on a trip in the spring to Mexico,” says Roche, who had been dating Diggs for six years and shared an apartment with him. “Someone just stole it away within seconds.”

No charges have been laid in the case and Diggs' family and friends are still waiting for answers while they try to come to terms with his death.

In the meantime, they are using the senseless tragedy as a way to promote change and end violence in the Halifax Regional Municipality, and have organized a march against violence at the end of the month.

“This is something to honour him, not only him but other victims that have died because of violence,” says Provo.

The march against violence is set to take place Sept. 30. It will start at the Dartmouth Duck Pond, cross the MacDonald Bridge and finish at the Halifax Common.
