CHICAGO — For several hours following the arrest of an Ohio murder suspect, police maintained a vigilant watch outside his Chicago apartment.

The individual in custody, identified as Michael McKee, stands accused of the fatal shootings of 37-year-old dentist Spencer Tepe and 39-year-old Monique Tepe. The victims, who were discovered with gunshot wounds, were found in their Columbus, Ohio residence. Court documents reveal that McKee is Monique’s former husband.

At the time of his arrest, McKee was residing in a high-rise on the Near North Side of Chicago.

Footage acquired by Fox News Digital captured a uniformed police officer positioned outside McKee’s apartment on the 12th floor of the building shortly after the arrest.

A longtime resident who lives in the building said she was shocked to learn the suspect lived just floors away.

“I talked to him at the pool,” said Gera-Lind Kolarik, 72, who has lived in the building since the 1980s. “There was nothing that seemed unusual.”

Kolarik said she recognized McKee after seeing his photograph shared by a television reporter outside the building.

The following day, she recorded video of police guarding the apartment and later observed investigators removing boxes and clothing from the high-rise apartment.

“And I saw the door open and I saw officers bringing stuff out and putting it in the boxes, clothing. I saw clothing and things like that,” she said.

Kolarik also observed evidence trucks from the Columbus, Ohio, Police Department at the Chicago apartment building. Authorities have not detailed what evidence, if any, was recovered.

Residents at The Pierre, a luxury apartment built in the late 1920s, say the heavy police presence was unexpected in a building typically known for its quiet atmosphere.

“You never think something like this is happening right next door,” Kolarik said.

McKee appeared in a Rockford, Illinois, courtroom on Monday afternoon, where he waived his extradition rights, and his attorney indicated he will plead not guilty after going back to Ohio. 

He is charged with two counts of premeditated aggravated murder charges in Ohio in relation to Spencer and Monique’s deaths. McKee was booked at the Winnebago County Sheriff’s Office in Illinois.
