Investigators say shot his mother inside their home on Wisconsin Street near Puritan at 8:30 p.m. - which led to a 14-hour search including Detroit and Michigan State Police.
Officers found him a mile away from the house Friday morning after neighbors recognized the teen after a 14-hour search for the boy.
Detroit police say Thursday night the teen and his 38-year-old mother got into an argument after she tried to discipline him, shooting her twice.
"One part is a good ending," Chief James Craig said. "Now the work begins."
Neighbors recognized the teen Friday morning and reported it to police.
"I can't stress enough the importance of people speaking up," said Assistant Chief Steve Dolunt. "It keeps the community safer, the citizens safer and the officers safer."
Dolunt talked about the altercation which started when the boy's mother tried to discipline him.
"He didn't appreciate it," Dolunt said. "He got a gun, and shot his mother twice."
Those bullets hit his mother in the neck and shoulder while the teen fled. Police arrested his 16-year-old friend as an accessory hiding in an attic in his home on Stoepel.
At that house police discovered two guns there, but not the gun involved in the shooting.
"He's denying all knowledge of anything," Dolunt said. "We found him hiding in the attic of this house. He did it because he said he's afraid of the police."
Not long after, police say a neighbor called 911 telling police the 14-year-old was walking along Appoline near Keeler. That was when an undercover officer approached the teen and arrested him without incident.
"The cadre of officers involved in this certainly were relentless," Craig said. "They wanted to find him, they wanted to bring him into custody, safely."
His mother, originally in critical condition was downgraded to serious condition, is expected to recover.
Detroit police say that no charges have been filed yet.
"We're certainly going to do everything we can to provide support to the family," Craig said. "Now it's in the prosecutor's and court's hands."
