INDIANAPOLIS – An investigation is underway after at least two people were killed and five others were injured in a shooting on Indy’s northwest side on Sunday morning.

According to the Indianapolis Metropolitan Police Department, just after 2 a.m., officers responded to the 6800 block of Shore Terrace on the report of shots fired.

IMPD said a total of six males and one female were shot in the incident. The two individuals who were shot and killed were adult males, police said.

Investigators say officers found five victims shot at the scene, three of whom were transported to an area hospital in critical condition. The other two adult males were pronounced dead on scene, according to police.

IMPD said one victim went to a local fire department for assistance. A seventh victim arrived at an area hospital. They were listed in “serious, but stable condition,” police said.

Investigators said the shooting happened outside in a parking lot. At least one person of interest was detained.

“This is certainly heartbreaking, obviously, you know, we’ve had a busy night, our metro officers have been extremely busy and we’re doing everything that we can to hold those accountable responsible.” IMPD Sergeant William Young said, “It’s also our responsibility as adults to make sure that we act as adults and do everything that we can to keep ourselves safe.”

FOX59/CBS4 spoke to a man who said he witnessed the shooting. He said everything was calm until it wasn’t.

“I woke up from a nap and I noticed the scene around me and it was normal,” Perry Hilliard said, “Everyone was walking around, everyone was having a good time, drinking, socializing, and then out of nowhere, rapid gunfire… nonstop.”

He said he stayed in his car until the shooting stopped. When he got out, he saw families screaming, two people dead and another fighting for their life.

He said the last time he remembers something like this happening was years ago.

“Different bar, different name and maybe a different crowd. Ever since the change, it’s been quieter, less drama, less trouble. But yeah, this doesn’t happen often,” Hilliard said.

IMPD is asking anyone with information about this incident to call Detective Christopher Winter at the IMPD Homicide Office at (317)-327-3475 or e-mail the detective at Christopher.Winter@indy.gov, or to remain anonymous, call Crime Stoppers of Central Indiana at (317)-262-8477
