Four teens were taken into custody in connection with a shooting on Tuesday that killed one teen and injured another in Pontiac, Michigan.

In an update on Wednesday, the Oakland County Sheriff's Office said a 13-year-old and a 15-year-old were arrested shortly after the shooting on gun charges. A 17-year-old was arrested at about 4 p.m. on Wednesday. Their identities have not been released.

The sheriff's office said a fourth suspect, 16, was taken into custody Wednesday evening.

"Individuals that clearly knew each other and, for whatever reason, used guns to shoot, and now we have a tragedy. One person dead, one person critical, and everyone's life is permanently changed," said Sheriff Michael Bouchard.

The shooting happened at about 7:49 p.m. on July 8 in the area of West South Boulevard and Highland Avenue.

Omarrel Shahon Ford Jr., 18, was killed and his 19-year-old brother was in critical condition, according to the sheriff's office. Ford Jr.'s grandmother and guardian says she is fed up with violence involving youth.

"I miss him so much, and it's hard because his brother is in the hospital too," said Barbara Watson. "He was loving and caring, you know, with the greatest respect for me, cause I went and got him."

Deputies identified a third victim, but that person was not injured.

The sheriff's office said investigators found the 18-year-old unresponsive with a gunshot wound to his chest. He was taken to the hospital, where he died from his injuries. The 19-year-old man was taken to a hospital by a citizen and is expected to survive, according to the sheriff's office.

An investigation is ongoing.

Anyone with information on the shooting is asked to call the Oakland County Sheriff's Office at 248-858-4950 or Crime Stoppers at 800-Speak Up.
