The teen's family says the trauma of losing him was magnified by the fact his siblings witnessed what happened after he ran back into the house for help.
His mother says her son didn't deserve this, and what he deserves now is justice.
The shooting happened around 4:30 p.m. Friday in the 300 block of West 11th Street in Michigan City, Indiana, police said.
Officer responded to the scene, where they found 14-year-old Devin Porter inside a home with a gunshot wound. He was taken to a hospital, where he was later pronounced dead.
India Harrington says the last time spoke with her son he asked if he could go play basketball.
"He was 14. We were just talking about his birthday on the 24th. Now I gotta talk about burying my son," Harrington said. "He was going the Y[MCA] out here, play ball... Next thing, I'm getting a phone call, my son gone."
Porter's sister says the shooting happened in broad daylight. She says she heard multiple gun shots before her 14-year-old brother ran into her room and collapsed as his young siblings took cover.
"His blood was on my hand," she said. "We tried to turn him over. He was still trying to gasp for air, but his eyes was gone in the back of his head by the time they came, he was gone."
Porter was a freshman at Michigan City High School. His mother said he was an honor roll student, beloved by his teachers. One of his true passions was basketball.

"My son didn't deserve this," Harrington said. "He ain't do nothing to nobody. All he wanted to do is basketball, that's all my baby wanted to do, and they took that from him."
Porter's family is scared to return to their home, concerned over what they called a recent uptick in shootings. A day before her son was killed, Michigan City Police say another juvenile was shot in the foot about half a mile away from their home.
"These kids is... innocent out here, getting hurt, killed, and all they, they don't deserve this," Harrington said. "My son didn't deserve this. He didn't do nothing to nobody."
Police say detectives are continuing to interview witnesses and search for surveillance video.
Anyone with information about the deadly shooting has been asked to contact the Michigan City Police Department.
No arrests have been made and no further information was available as police continue to investigate.
