A 19-year-old Washington woman is facing serious charges after police say her own parents uncovered chilling plans in her journal — including a detailed intent to kill her ex-boyfriend — before she was caught on a Ring camera creeping around his home in the middle of the night with a shotgun.

Authorities say Trinity Morley of Kent was arrested on July 27 in Maple Valley after her parents, alarmed by what they’d read, called police to report what looked like an unfolding crisis. The notes prosecutors later presented in court are disturbing in both tone and detail. “I have the gun now, three rounds of buckshot,” one entry reads. “The shotgun is heavy. He told me that if I don’t hold it right, my arm will get blown off. I have three chances to get this right and I don’t want to resort to knives.”

When deputies responded to the family’s call for a welfare check, Morley was already gone. She had set off for the home of her former boyfriend, who hasn’t been publicly identified. He wasn’t there, but his father and family were — and they soon found themselves hiding upstairs in fear.

According to police, the father had been watching the house’s Ring camera feed when he saw a masked and hooded figure staring directly into the lens. That figure, investigators later said, was Morley. He told deputies that he quickly rushed his family upstairs, fearing the intruder was armed.

Surveillance video reviewed by the King County Sheriff’s Office shows a figure prowling outside the residence, moving toward the door while holding what appears to be a shotgun. Prosecutors allege that Morley tried to get inside but retreated when she realized the family was home.

Deputies, already combing the area, spotted her nearby thanks to a drone. They found her on a dock, still in possession of both a shotgun and a knife. Body camera footage from the arrest shows deputies shining flashlights and speaking calmly, trying to coax her to surrender. After a tense few moments, she complied and was taken into custody without incident.

What came after has made the case all the more unsettling. Prosecutors said Morley displayed what they described as an “eerie” demeanor, smiling, rolling her eyes, even joking with officers. At one point, according to FOX 13, she looked at a deputy writing up notes and remarked, “It’s a good story.”

Prosecutors say she admitted she intended not only to kill her ex, but also to provoke a deadly confrontation with police — what’s often called “suicide by cop.”

Investigators also found notes written to her current boyfriend, apologizing for lying to him to obtain the shotgun. She had allegedly told him she needed it for protection. Instead, she carried it to her ex’s family home.

Morley is now charged with first-degree attempted murder along with weapons violations. She was arraigned in August and is being held at the King County Jail on $500,000 bail. Court records did not indicate how she intends to plead.

For the ex-boyfriend’s family, the close call left them shaken. His father told investigators he hadn’t recognized the figure outside the home until deputies identified her. In hindsight, the moment feels like something out of a nightmare — a masked face appearing on a security camera feed, followed by the realization that it was someone they once knew.

For Morley’s parents, the story is no less grim. They discovered the plans in their daughter’s own handwriting, alerted authorities, and ultimately may have prevented a tragedy.

The case now moves to trial, but the reverberations — of fear, betrayal, and what could have been — linger in Maple Valley.
