INDIANAPOLIS, Ind. – We are digging deeper in troubling notes and Facebook posts by the suspect in a Zionsville homicide and shooting up of two IMPD district headquarters.

Police arrested 21-year-old Damoine Wilcoxson on Monday after a standoff on the city’s northeast side.

A retired homicide detective said Wilcoxson likely would’ve continued his violent spree until he was arrested.

The Boone County prosecutor said the Zionsville homicide victim, 82-year-old Jac Clements, was randomly chosen, but it’s possible that the Zionsville community could have been targeted.

“You know, you take a look at the posts. He was saying some things that fit the Zionsville community profile, and Mr. Clements just happened to be in the wrong place at the wrong time,” said Todd Meyer, Boone County Prosecutor.

Those statements came in a variety of forms. Court papers indicate that notes left at the IMPD station shootings contained phrases like “whites must die” and “whites will drop,” along with threats toward women and children.

Facebook posts by Wilcoxson included references to social justice and the Nazis plan to get rid of the Jews.

“Looked to me like a very angry man. He’s holding a lot of anger in, and this is the way he’s expressing it. Somehow he sees his problems being blamed on other people, and he’s very angry about it,” said Robert Snow.

Snow is a retired homicide captain for Indianapolis police. He said based on the notes and social media postings, the alleged violence was a demonstration of anger, using Facebook as a sounding board.

“These long rambling manifestos are usually a sign of some kind of psychological pathology, something wrong with them mentally,” said Snow.

On September 28, investigators said Wilcoxson shot Clements in Zionsville, leaving him in his driveway to die, without a clear motive. It’s a type of homicide that Snow said is very rare.

“It could’ve been anybody. It could be anybody. It has no relationship at all to the murderer, just picked at random, out of thin air,” said Snow.

The two IMPD police stations would be shot up in the following days.

Snow said the multi-county crime spree is disturbing but not uncommon when dealing with a suspect with a profile like Wilcoxson.

Wilcoxson told a Boone County judge during his court appearance on Tuesday that he did not want an attorney, and the judge advised him that it’s a bad idea to represent yourself. He faces 65 years in prison if convicted on the murder charge.

Charges in Marion County with respect to the police station shootings have not yet been filed.
