A Philadelphia teen was shot and killed on his way to school earlier this week, shortly after telling his mother that he loved her.

Devin Weedon, 15, was shot in the chest while walking to Simon Gratz High School on Monday morning. The high school sophomore was reportedly in an altercation with three male suspects.

"He was an all-around good kid, he didn't cause trouble, he didn't bother anyone," Devin's mother Wytina Burnside told FOX 29 Philadelphia. "He was trying to start his own athletic club for the youth."

"'I love you mom, have a good day.' That was the last thing he said to me," she added.

Devin's father Gary Weedon believes that his son, who was an excellent student, was defending himself during the altercation.

"I know why they shot him…because he got the best of them. When you get the best of three dudes, you know, your feelings and emotions get involved," Weedon said.

"People are dying, kids are getting killed," the grieving father added. "I'm telling everybody, you got kids, wife, grandkids, whatever, give them a hug and tell them you love them every morning, cause you never know when you're never gonna see them again."

Police are searching for the three suspects involved in the shooting.
