Fresh insights have surfaced in the ongoing legal proceedings concerning a Colorado resident who purportedly claimed to have “accidentally” discharged his firearm, resulting in his wife’s fatal chest wound. This incident, he alleged, occurred while he was “clearing his gun.” He further stated that he engaged in CPR for nearly an hour before reaching out to emergency services.

David O’Grady, aged 37, faces serious charges, including one count of first-degree murder and a count of domestic violence. These charges have been officially recorded by the Arapahoe County Sheriff’s Office, as previously highlighted by Law&Crime.

The tragic event unfolded on the morning of September 7 at the couple’s home on Shawnee Way in Aurora. This incident led to the untimely death of Taylor Dawn Last, O’Grady’s 29-year-old wife.

Initially, upon his arrest, O’Grady claimed that his delay in contacting emergency services—approximately an hour—was due to his attempts at performing CPR. However, investigators now suspect that he may have postponed the call for help for several hours.

These revelations add another layer of complexity to an already troubling case.

That initial charging document says O’Grady told a dispatcher he was “clearing his gun last night, but accidentally discharged his firearm and hit his wife in the chest.”

While dispatchers heard the hourlong version of the story, O’Grady allegedly told responding sheriff’s deputies his wife had been dead for several hours by the time they arrived at around 7:45 a.m., according to court documents recently obtained by The Denver Post.

At the time of the shooting, the couple’s two children, a 6-year-old and a 4-year-old, were sleeping in the house, according to the original affidavit obtained by Law&Crime. Also present was O’Grady’s mother.

Deputies were allowed in the home by the defendant and found Last “lying on her back on the ground, with her left arm on her chest,” the affidavit says. The document describes the victim’s body as “cold and stiff to the touch, indicating that Taylor had been dead for a while.”

In his initial interview, O’Grady allegedly admitted he and Last had been arguing about some kind of a party. As the argument 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.

Last was struck in the chest by the bullet and died, authorities say.

As the shot rang out, the other inhabitants took note.

The couple’s children slept in a shared bedroom upstairs across a “narrow hallway” from their parents’ bedroom, according to law enforcement. The children allegedly told investigators they heard “loud arguing” and a “bang” that caused them to “jump” out of bed, the affidavit says.

The children also allegedly 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. The couple’s children also said they saw “[b]roken colorful things” on the ground in the immediate aftermath, authorities allege. But, notably, “none” of those purported items were visible when law enforcement arrived.

In a GoFundMe, Last’s aunt 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 online fundraiser reads. “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.”
