Court documents say a police officer fatally shot in Indianapolis sustained 14 gunshot wounds.

WISH-TV reports the documents say Homecroft Police Maj. C.T. Bowman responded to a car crash Thursday with the officer who was slain, Southport Police Lt. Aaron Allan. Bowman says driver Jason Brown was upside-down in the vehicle and being held in by his seat belt. He says Brown was "hysterical" and Allan told Brown to be calm.

Bowman says Allan climbed into the car, then Bowman turned to speak to a female witness when shots rang out. Bowman said he heard 10 or 12 gunshots followed by a lull, then two or three additional shots.

The 28-year-old Brown has been arrested on a preliminary murder charge. Police say he's being detained at a hospital with non-life-threatening injuries.

A 28-year-old Indianapolis man arrested in the fatal shooting of a police officer will remain in custody without bond until next week.

The prosecutor's office in Indianapolis said Friday that a judge granted its request that Jason Brown be held without bond until a Tuesday court hearing. Brown is a suspect in the death of Southport police Lt. Aaron Allan.

Authorities say Allan was shot Thursday afternoon while trying to help two people inside an overturned car just outside the municipality's limits on the south side of Indianapolis.

Brown was arrested on a preliminary murder charge, but police haven't given a possible motive. Police say he's being detained at a hospital with non-life-threatening injuries.

Marion County prosecutor's office spokeswoman Peg McLeish says prosecutors expect to decide on filing formal charges in the shooting early next week. McLeish says the second person in the car hasn't been arrested.

A police chief says one of his officers had no reason to suspect he was in danger before he was fatally shot while trying to help two people inside an overturned car on a busy Indianapolis street.

Authorities say Southport police Lt. Aaron Allan was shot Thursday afternoon after reaching the crash scene just outside the municipality's limits on the south side of Indianapolis.

Twenty-eight-year-old Jason Brown has been arrested on a preliminary murder charge but police haven't given a possible motive.

Southport Chief Thomas Vaughn says other officers and the community don't understand the shooting because Allan was trying to help the crash victims, not arrest anyone.

Vaughn says the car wasn't stolen and no warrants were pending for the man arrested in the shooting.

Vaughn says the 38-year-old Allan was married and the father of two sons.
