INDIANAPOLIS — Three people were found dead inside a residence Sunday after police were on the scene of an armed, barricaded subject on Indy’s west side for over four hours.

According to the Indianapolis Metropolitan Police Department, officers were dispatched around 2:20 p.m. Sunday to the 1700 block of Countryside Drive on Indy’s west side in reference to a shots fired disturbance report. The incident soon turned into what preliminary information shows to be a double homicide and suicide.

Upon arrival, IMPD officers said they found an adult man with a firearm outside a residence and briefly spoke with him. Officers said the man then fled inside and fired an unconfirmed number of shots. They also said they believe that this man shot at officers from inside the home.

Due to police confirming shots fired, IMPD officers contacted SWAT. Members of the SWAT team attempted to contact the man inside for multiple hours, police said, but were unsuccessful.

After failed attempts to speak with the man, SWAT made entry into the barricaded residence. Inside, police said they found three people dead from gunshot wounds: one female and two males. IMPD has not released their identities.

However, IMPD detectives did confirm Sunday that one of the dead men found inside is likely the man officers initially made contact with. They also confirmed that three dead people appeared to die from gunshot wounds.

Detectives from the IMPD Critical Incident Response Team are currently conducting a death investigation, police said.
