Authorities are searching for two suspects after a recent Temple University graduate was gunned down while walking his dog.

CBS Philly reports that the incident happened at around 7 p.m., only a block from the 25-year-old Milan Loncar’s house. According to the police, two people approached Loncar near 31st and Jefferson streets in Brewerytown and demanded to search his pockets. One of the suspects then shot the victim in the chest.

Authorities found Loncar on the ground, still holding onto his dog’s leash. First responders rushed him to the Temple University Hospital, but he was pronounced dead around 30 minutes later.

“Two males that were walking west on Jefferson approached the victim. One stood in front of him, one stood behind him. You can clearly see that they were reaching into his pockets, and then one shot was fired,” Philadelphia Police Chief Inspector Scott Small said.

On Thursday, Philadelphia authorities released security footage of the incident.

“He was going to move in with his girlfriend in March. He had graduated and had his first job and was just starting out,” the victim’s mother, Amy Lounsberry, told 6 ABC.

“I don’t know why they did it. I can’t understand. They didn’t get any money. Did they need it so badly or were they trying to show off?”

Both suspects are still at large. A $20,000 reward is being offered for information that leads to their arrests.

• Suspect one is a Black male with a slightly husky build, seen wearing a black face mask, black baseball cap, black hooded jacket, and athletic shoes.
• Suspect two is a thin Black male with a medium build, seen wearing a white face mask, puffy hooded black jacket, blue jeans with lights spots on them, and athletic shoes.

“I don’t think he even verbally fights with anybody. He was always really cool and polite. I just can’t believe this happened to him,” the victim’s uncle, Nikola Loncar, said.

Anyone with any information about the incident is urged to contact police at 215-686-TIPS, or email tips to @phillypolice.com.
