A $1,000 reward is being offered to help solve a Christmas Day murder.
Phoenix police are looking for any information that will help them find out who killed 41-year-old Isaac Rivera.
"He was just going to go to the store to buy a soda," said Rudy Rivera, the victim's father.
His family said he was only going to be gone for 30 minutes.
"But he never came back home," said Rivera.
Police said Isaac Rivera was stabbed around 5:30 p.m. after leaving the Circle K near 83rd Avenue and Thomas Road.
"It's the worst call a parent can get," said Emma Radzinski, the victim's mother.
A stranger drove him to the hospital, but unfortunately, that's where he died.
"It is so hard that we will never see him again," said Radzinski.
But what is hard is not knowing who killed their son.
"Someone had to have seen something," said Radzinski.
"I know they will catch him. I hope he gets what he deserves," said Rivera.
Rivera leaves behind a fiance and two children.
The family has set up a GoFund Me account to help pay for funeral expenses.
A concert fundraiser is being held on Jan. 2. It will be at Chopper Johns at 2547 E. Indian School Road at 8 p.m.
