Chris Mohan, 22, of Surreyand Edward J. Schellenberg, 55, of Abbotsford got caught "in the wrong place at the wrong time," when the killings took place at a 15th floor unit, police said.

Mohan was a fun-loving young man who wanted to become a fitness trainer, said his cousin Shiris Nand.

"The loss of Christopher Mohan was a great tragedy and the family is still in a state of shock and disbelief," Nand said Tuesday on behalf of the Mohan family.

Tributes poured in for Mohan on a Facebook memorial site, where friends remembered him as a happy guy who always had a smile on his face.

Mohan, a shelf stocker at a liquor store,was born and raised in Surrey, went to Queen Elizabeth Secondary School and had been living on the 14th floor at the Balmoral Tower at 9830 East Whalley Ring Road.

Last week, he moved to a bigger suite on the 15th floor, where the slayings took place at Apt. 1505, police said.

Families ask for privacy

The families of Mohan and Schellenberg requested privacy to grieve their losses.

Jim Penner, the pastor at Immanuel Fellowship Baptist Church where Schellenberg attended, described him as "a deeply loved husband, father and brother to many."

"Ed gave tirelessly to church, friends and neighbours,"said Penneron behalf of the Schellenberg family. "He was a cheerful, well-respected businessman, a handy man and an outdoors enthusiast."

Schellenberg was an active member of the church and friends told CBC News he was always doing something to help out — everything from ushering at the church to weeding in the garden outside.

"Ed would have have come out in the middle of the night in the worst storm in the Fraser Valley and helped you," said Glenn Spratt, a family friend.

Schellenberg, a gas repair man, was servicing fireplaces in the Balmoral Tower on Friday. His nephew was apprenticing with him that day.

"[Schellenberg] released that family member to go home from work because he was finished and Ed assumed the responsibility of finishing the work and that was the last contact he had," Penner said.

That last job is what took Schellenberg to the 15th floor, he said.

A memorial service called "the celebration of Ed's life" is scheduled at 11 a.m. Saturday, Penner said.
