A 33-year-old Seattle woman killed her father with an ice ax after the couple argued about keeping the lights off on Election Day, prosecutors alleged last week.

Corey Burke, who “appeared to be having a mental health crisis,” is accused of murdering Timothy Burke, 67, inside his Seattle home around 8 p.m. last Tuesday, King County prosecutors wrote in charging documents obtained by The Post.

Authorities saw Corey leaving the home in Rainier Valley with blood on his face after he allegedly broke the home’s windows.

When police entered, they found Timothy’s body with injuries to his head and torso, including 2-inch lacerations to his ribcage, doctors said.

Another puncture wound was near the base of his skull.

Police also found a silver and blue ice climbing spike with blood on it.

Corey, who was sent to the hospital for a mental health evaluation, allegedly confessed to investigators the next day that she killed her father with the ax and also by strangling him. He also admitted to biting his father while strangling him, doctors alleged.

“Corey said … when her father started arguing with her about the lights going out, that she ‘just freaked out,’” according to the documents.

“The defendant told detectives that she knew she couldn’t convince him to keep the lights off, so she went upstairs, retrieved an ice ax and tripped her father, strangled him with the ax and her hands and then bit him and killed him. hit several times. on the head and side with the blunt and sharp ends of the ice ax,” according to a summary of the case prepared by the prosecution.

The daughter was charged with first-degree murder. She is being held at the county detention center on $2 million bail, according to court records.

Corey had described a strained relationship with her father and told police she felt “hyperfocused and disorganized when it came to her own attachment to her father,” according to doctors.

She “did not appear fit to care for herself” and was a danger to herself, court filings state.

His arraignment is scheduled for November 21.
