Authorities in Pennsylvania are looking for a couple seen walking hand in hand just after a 15-year-old boy was fatally stabbed Friday night in Upper Darby.

Officials said Michael Garr, a 10th grader at Upper Darby High School, was stabbed in the neck just after 9:30 p.m. and died after he went into cardiac arrest, WPVI reported. He was pronounced dead on the scene.

On Sunday, Upper Darby Police released the blurry photo of the couple walking on the same street at 9:39 p.m. Friday night.

“It’s terrible,” said schools Superintendent Timothy Bernhardt, WPVI reported. “How do you get to a point where kids this age can commit some type of act of violence like this? There’s no words to explain it. Our hearts go out to the family, we ask everyone to keep the family in their thoughts and prayers.”

The district released a statement saying counseling support would be available at schools on Monday.

Community members have come together to support Garr’s family.

“As many prayers as we can get is probably the best that we can ask for because we’re all heartbroken,” said Chris Kolody. “The Garr family is such a great family, and I think ultimately we’re just speechless.”

Gambol’s Big G Cafe is collecting donations for the family.

“Everyone that comes in here has literally been coming in here for like 30 plus years, so everyone knows everyone. It’s like a big family,” said Mallory Cook, the manager of the cafe.

The Delaware County Fraternal Order of Police has offered a $5,000 reward for a tip leading to an arrest. Police ask anyone with information to call detectives at 484-574-1157. They’re also looking for surveillance video between 8 and 11 p.m. on Friday in the Oakview section of Drexel Hill or along the Baltimore Pike corridor in Clifton Heights.
