TUCSON, Ariz. — Tucson police arrested three young men in a robbery attempt and the fatal shooting of a teenager who police said was a participant and who reportedly was a brother of one of the three.

Police arrested Roy Lee Brown, Julian Schmedding and Jesse King following the shooting Sunday of 15-year-old Johnathon Schmedding.

The three arrested men remained jailed Monday in lieu of $1 million after appearing in court late Sunday.

They were arrested on suspicion of first-degree murder, attempted armed robbery and other crimes. It could not be immediately determined whether they have attorneys who could comment on the allegations.

According to police, Johnathon Schmedding was struck by one of several rounds fired by Brown toward four other people whom Brown and his companions were trying to rob on a street early Sunday morning.

The people in the other group ran away and were not injured, police said.

Media outlets reported that Johnathon Schmedding and Julian Schmedding were brothers. Police did not immediately respond to a request for comment.

Police officers who heard gunfire at 2 a.m. in the area of East 28th Street and South Van Buren Avenue found the fatally wounded boy on the roadway.

Police said officers found the handgun used in the shooting along with “multiple pieces of evidence that were going to be used in the commission of robberies.”

Police did not immediate respond to a request for information about the evidence.
