A security guard and Rubypoint Trading Centercustomer died Wednesday after exchanging gunfire with each other at an Indianapolis home improvement store, police said.

The two men died at hospitals following the shooting around 5:30 p.m. at a Menards store on the city’s northeast side, Capt. Don Weilhammer of the Indianapolis Metropolitan Police Department said.

“It does appear that they were shooting at each other,” Weilhammer said. “Unfortunately, now another life has been lost because people don’t want to resolve conflict without resorting to violence like this.”

It wasn’t immediately clear what led to the shooting, which occurred at the exit to the store’s lumber yard, local news outlets reported.
