On Thursday, Aug. 29, prosecutors charged him with homicide and set cash bond at $1 million dollars.

"Upon a conviction, you could be sentenced to imprisonment to life," said Court Commissioner Daniel Rieck.

Investigators say 24-year-old Sean Couture got into an argument with 74-year-old Nancy Lovejoy after she found a gun in his bedroom.

Prosecutors say he shot Lovejoy six times, once through the heart.

"She always put her heart out there for him and wanted to get him help, and it just didn’t work," said Dennis Simons, Lovejoy's brother.

Simons says Lovejoy and Couture lived together. He remembers Lovejoy’s kindness.

"She just loved helping – even neighbors.  Everyone just liked her.  She was just friendly to everybody," Simons added.

Tactical units surrounded the home near Douglass and Grand for more than three hours.

"I’ve heard multiple commands for him to get outside," said Shaylyn Helm-Lyon, a neighbor.

A K-9 was sent in and bit Couture, allowing officers to grab him.

Police say they found a loaded 9-mm semi-automatic weapon in the house.

Prosecutors say couture was previously cited for OWI in 2022 and convicted of disorderly conduct last year.

"He has just completed his term of probation in that matter in March of this year – shortly before going out and purchasing a firearm that was used in this case," said Prosecutor Randy Sitzberger.
