“I need an ambulance real quick. Shots have been fired. People are dead,” Steven Chabot said to the emergency dispatcher. “I’m shot. I’m shot.”

Chabot was hiding in the bedroom closet of his Saco house, bleeding on the floor, when he called 911 on Dec. 18, 2014.

Chabot had been shot several times by a masked intruder. He thought his wife, Carol, had been murdered by the gunman. He was wrong: She was hiding unharmed in another bedroom.

But he was correct that their houseguest, Rachel Owens, his wife’s childhood friend of nearly 50 years, had been shot several times. Like Steven Chabot, she survived.

Jurors listened to that 911 recording during the first day of the federal trial of Gregory Owens, who has been charged with shooting his wife, Rachel Owens, and Steven Chabot during a staged break-in at the Chabots’ home.

The trial in U.S. District Court in Portland is the first of two cases that authorities have brought against Owens, 59, of Londonderry, New Hampshire, for the shootings and break-in.

Owens also faces multiple state charges, including aggravated attempted murder. His trial on those charges in York County Superior Court in Alfred has not been set and depends in part on the outcome of the federal trial, which is expected to take more than two weeks.

Owens is charged with two federal counts: interstate domestic violence, punishable by up to 20 years in prison, and using a firearm during and in relation to a crime of violence, punishable by up to life in prison. He has pleaded not guilty.

Carol Chabot testified as the first witness at the trial, describing how she awoke in the upstairs bedroom of her home at 25 Hillview Ave. in Saco after hearing a window shatter downstairs.

“I’m a very light sleeper. I kind of elbowed my husband because it didn’t sound right,” she said. “I heard the second shatter when I was entering the hallway to go check on Rachel.”

Assistant U.S. Attorney Darcie McElwee, who is prosecuting the case, said in her opening statement in the trial that witnesses would testify that the intruder broke through the outside door into the garage of the Chabots’ home by breaking a glass pane and then got into the house from the garage by breaking the window of a second door.

“It sounded like someone threw a table through my sliding doors to my deck. It was so loud,” Carol Chabot said.

Steven Chabot, the second witness, testified that he came out of his bedroom after hearing the glass smash and faced an intruder running up the stairs with a pistol in his hand, wearing a black ski mask.

Chabot said he first retreated to his bedroom and then came back to the bedroom door after hearing many gunshots. In the doorway, he faced the intruder again.

“I was defenseless. I was scared. I wasn’t able to help my wife,” Steven Chabot said. “I wasn’t sure what was going on. Then I heard the gunshots, and it was like, ‘What’s happening?'”

In the subsequent 911 call, he pleaded with the dispatcher for about 10 minutes until police finally arrived.

“I’m losing a lot of blood. Please hurry,” he said in the recorded call played for jurors.

After about eight minutes, he could be heard on the call praying.

Police investigating the shooting pulled over Gregory Owens about three hours after the 911 call as he was driving his Hyundai Santa Fe sport utility vehicle in Hudson, New Hampshire. Investigators later collected DNA evidence from Owens that matched DNA on the outside door of the Chabots’ garage. They also collected DNA evidence from bloodstains on the steering wheel and armrest of Owens’ vehicle, according to a report filed by FBI Agent Pamela Flick to obtain search warrants in the investigation.

Owens is a former Army marksman who investigators believe tried to kill his wife after his girlfriend in Wisconsin threatened to expose their affair.

Owens’ attorney, Sarah Churchill, denied the government’s allegations in her opening statement. She said Owens cut his hand on a broken glass in his kitchen in New Hampshire while working overnight on a business contract proposal and went out during the night in his vehicle to go to Dunkin’ Donuts.

“Greg Owens did not shoot his wife. Greg Owens did not shoot Steve Chabot. Greg Owens did not break into the Chabots’ home at 25 Hillview Drive,” Churchill said.

Churchill said the police timeline that says Owens drove in the night from Londonderry to Saco doesn’t make sense. She said it would have taken longer for Owens to have driven that far, that highway video footage shows no sign of Owens’ vehicle and that video footage from Dunkin’ Donuts in New Hampshire shows he was there.

Police never recovered the gun used in the shooting.

When the trial resumes on Wednesday, McElwee said she next plans to call Rachel Owens to testify.
