A Michigan father pleaded guilty this week to the cold-blooded murder of his 20-year-old daughter, who he beat to death with a baseball bat while she slept.

Authorities say Robert Kelly, a psychologist from Oxford, Mich., walked into his daughter Megan’s room one night last May, bludgeoned her in the head, then walked to the police station to confess.

“I asked him if he knew who did it,” police dispatcher Tony Van Houten testified, according to the Detroit Free Press. “And he stated, ‘Yes, I did.’”

Megan Roberts, Kelly’s only child, fell into a coma and died two months later, on July 27, according to the Associated Press.

Police say they are puzzled by the brutal murder as investigators found no motive.

“I’ve handled over 60 murder cases, and this is the strangest one,” defense lawyer Sanford Schulman told the Detroit Free Press.

Schulman said Kelly, who has a history of depression but not mental illness, was “unable to distinguish right from wrong on the night he did this.”

Kelly pleaded guilty Wednesday to second-degree murder, in exchange for the court dropping a first-degree murder charge, the newspaper reports. He’s expected to get 20 to 30 years in prison at his sentencing on July 11.

“From what we can tell, he loved his daughter deeply,” Schulman said. “They were very close. It was something in him that snapped. So that’s why this plea deal seemed appropriate.”
