On April 6, at Taz's Convenience Store in downtown an employee told ABC11 the owner, Taiseer Zarka, accused Garrity of shoplifting and asked him to open his bag.
When he refused they allegedly got into a fight that left Garrity stabbed multiple times.
He died at the hospital.
Last week ABC11 spoke to Garrity's family about their loss.
"He really was a big kid at heart and it's just indescribable," said his mother Amy Garrity.
"No parent should ever have to go through this pain," said his father Mark Garrity Sr.
Police say that Zarka was arrested without incident.
