Updated:ORLANDO, Fla. —
Family and friends of a man who was stabbed to death at an Orlando shopping center comforted each other during a vigil Wednesday night.
The vigil was held at the spot LaQuincy Johnson, 32, was murdered.
Family members and friends wiped away tears as they released 32 ballons in his honor.
Johnson was stabbed to death in the parking lot of a Washington Shores shopping center Sunday.
His mother stood alongside his 12 brothers and sisters Wednesday. She said she still can't make sense of her son's death.
"That's my child, and you took my child's life and you can't get that back," said Cynthia Williams.
Orlando police are looking for LeCarlos Williams -- calling him a person of interest in Johnson's murder.
Authorities aren't saying what provoked the attack, but Johnson's mother said it was over a $15 debt.
"I'm asking for [a charge of] first-degree, pre-meditated murder, because that's what it is. Over something senseless," Williams said.
Records show Johnson had a criminal history and served time in prison for robbery with a deadly weapon, drug charges and theft. But he hadn’t been arrested in Orlando in more than three years.
In that time, his mother said, he cleaned up his act.
"My son had turned his life around. My son went to school and he had a job," Williams said. "It's hard, it's hard, it's very hard.”
Anyone with information in Johnson's murder is asked to call Orlando police.
