She hid in a bedroom closet until he came home.
It’s not clear for how long, or exactly when she broke into her ex-boyfriend’s house, but as soon as he and another man walked inside, she popped out, brandishing a 9 mm handgun and a knife, police said.
Detectives don’t know the motivation behind the deadly violence that followed inside the house on Kuhn Lake on Wednesday night.
What they do know is that officers had been called to handle domestic disputes between Sonya Lynn Armontrout and Steven Carman multiple times throughout the years.
They also know the pair had been embroiled in multiple custody battles over their two young daughters, both of whom were in the home at the time.
Police said Armontrout unleashed a barrage of gunfire that left Carman’s friend injured and Carman – shot multiple times in the head “execution-style” – dead.
Armontrout, 42, of Warsaw, is currently in jail without bail facing preliminary counts of murder, attempted murder and burglary.
According to the Kosciusko County Sheriff’s Department, officers were called to 44 EMS B10 Lane, just south of North Webster, at 7:18 p.m. There, they found Joseph A. Glant, 54, of Warsaw, suffering from at least one gunshot wound.
They also found Armontrout and her two daughters, ages 5 and 6, Sgt. Chad Hill of the Kosciusko County Sheriff’s Department said.
Carman had custody of both children at the time, Hill said.
Investigators also found Carman, who they believed was suffering from critical gunshot wounds until medics and the Kosciusko County coroner arrived.
The 51-year-old was pronounced dead at the scene.
Piecing together what happened, detectives believe that Armontrout waited in the closet for Carman to get home.
When the two men came inside, she came out and fired her gun, hitting Glant in the lower torso, police said.
He was able to stumble away and call police at some point, Hill said.
One of Armontrout’s daughters also called 911 as the shots began to ring out, Hill said.
After shooting Glant, Armontrout turned her attention to Carman, police said. She’s accused of firing the gun multiple times and striking him in the chest.
Carman began to stumble down a hallway toward the home’s living room.
Before he could get there, though, police believe Armontrout attacked him with a knife and stabbed him in the back multiple times.
The pair ended up in the living room, and that’s where Armontrout is accused of delivering the fatal shots.
“She turned the gun in an execution-style manner and shot him in the head multiple times,” Hill said.
Glant was taken to a hospital with non-life-threatening injuries, according to police. At the scene, police confiscated the gun and knife used in Carman’s killing.
Armontrout’s and Carman’s children were uninjured amid the gunfire.
Wednesday evening, the girls were placed in the custody of Indiana’s Department of Child Services, according to police.
The case remains under investigation.
