A Colorado man claims he “accidentally” shot his wife in the chest while “clearing his gun” and then “attempted CPR for about an hour” before finally calling 911 to report what happened, cops say.
David O’Grady, 36, is facing domestic violence and first-degree murder charges for the Sept. 7 shooting at the couple’s home in the 5200 block of Shawnee Way in Aurora, according to court records and the Arapahoe County Sheriff’s Office.
His wife, Taylor Dawn Last, 29, was found dead inside the home after officers responded on Sunday morning at around 7:45 a.m., O’Grady’s arrest affidavit alleges.
After calling 911, O’Grady allegedly told a dispatcher that he was “clearing his gun last night, but accidentally discharged his firearm and hit his wife in the chest,” according to the affidavit, which was obtained by Law&Crime on Wednesday.
“He attempted CPR for about an hour before calling 911,” the document says.

The couple’s two children, ages 6 and 4, were sleeping in the house and O’Grady’s mom was also there. “Upon arriving on the scene, David said that the victim had been dead for several hours,” the affidavit notes.
O’Grady let the cops inside the couple’s Aurora home and they found Last “lying on her back on the ground, with her left arm on her chest,” the affidavit states. “Taylor’s body was cold and stiff to the touch, indicating that Taylor had been dead for a while,” police allege.
Authorities questioned O’Grady about what happened and he allegedly admitted that he and Last “had been in a verbal argument.” As the fight unfolded, “David said he knew the gun was loaded, fired a round into the bed, and then, as Taylor was coming into the room, aimed it in Taylor’s direction and pulled the trigger,” according to the affidavit.
The bullet struck Last in the chest and she died from her injuries, police say.
The couple’s two kids were in a “shared bedroom” upstairs when the shooting happened, across a “narrow hallway” from their parents’ room, cops report. The children allegedly told investigators that they heard “loud arguing” and a “bang” that caused them to “jump” out of bed, the affidavit says.
The kids said they saw O’Grady “had thrown something” at Last and then she fell “onto the bed with her hands up in the air,” the affidavit alleges. “Broken colorful things” were allegedly observed on the ground, with “none” of the “broken” items being there when police arrived, cops say.
Last’s aunt, who has started a GoFundMe, describes her niece’s slaying as “an unimaginable tragedy” and “tragic act of domestic violence” that now leaves her two children without their mom and dad.
“She was a loving mother to her two beautiful little girls,” the fundraiser says, noting that the 4-year-old’s birthday is Wednesday. “The unthinkable happened — their father was responsible for her death, and he is now incarcerated. This leaves these sweet girls without both of their parents.”
Police officials told Law&Crime on Tuesday that O’Grady was in custody awaiting his first court hearing. He’s due to appear on Sept. 11 at 1:30 p.m., per online records.
