Officials from the St. Joseph County Metro Homicide Unit say a 16-year-old male connected to the fatal shooting of a teenager has been arrested after turning himself in and has been taken to the Juvenile Justice Center.

A 17-year-old boy who was shot on South Bend's west side Wednesday night was pronounced dead at the hospital early Thursday afternoon.

"Caller just called in stating he shot and killed his brother, and then disconnected."

A 911 call revealed tragedy inside a South Bend home in the 100 block of Woodhill Lane, near Washington High School.

St. Joseph County authorities say Darnell Tobar II was shot while visiting a friend in the home Wednesday night.

However, the dispatch call reveals the shooting may have been a mistake.

"He answered. Said... an accident. We don't have anything further at this time other than they were playing with the gun," the dispatcher said.

"Based on the investigation, the shooting is believed to have occurred after the juveniles were recklessly handling a gun," according to a release from the St. Joseph County Prosecutor's Office.

The 16-year-old suspect has not been publicly identified. Officials say he has been very cooperative with investigators.

He was arrested on preliminary suspicion of reckless homicide, which would be a level 5 felony if committed by an adult.

Officers responded just before 11 p.m. Part of the street and neighboring homes were still blocked off Thursday morning. The crime scene tape was completely removed around 2 p.m. Thursday.

"Very surprised that it happened on this street," neighbor Eric Hauguel said.

Most neighbors said they were alerted by the police response and did not hear any gunshots Wednesday night.

"Most of them are all quiet on this street, so it's kind of weird to hear a gunshot or hear that somebody shot somebody," Hauguel said.

Metro Homicide is leading the investigation. An autopsy has been scheduled for 9 a.m. Friday in Fort Wayne.
