The surgeon who has been arrested and charged with the murder of his ex-wife and her husband allegedly broke into their home weeks before their deaths.

Michael McKee, 39, was seen on video entering the “curtilage” of the Ohio home — meaning on the property, but not the home itself — owned by Spencer and Monique Tepe in Columbus on Dec. 6. He was then seen leaving a few hours later during a period when the Tepes were away, according to a probable cause affidavit unsealed in court and obtained by PEOPLE.

On that same night, Monique and Spencer were at the Big Ten Championship football game in Indiana with several other couples, according to the affidavit.

At some point during the evening, Monique excused herself and returned to the hotel room, prompting Spencer to later tell their friend she was “upset about something involving her ex-husband and he was going back to the hotel.”

The curtilage of the Tepe home is accessed via the back alleyway, which McKee is allegedly seen walking down in a person of interest video released by the Columbus Police Department.

Investigators also discovered that McKee was not on the schedule for the hospital at which he worked on Dec. 6, when he was allegedly seen at his wife’s home.

He would return to the Tepe home on Dec. 30, according to authorities — at which time he allegedly shot Monique, 39, and Spencer, 37, as their children slept just feet away.

McKee allegedly left his phone at work on Dec. 29, when, according to authorities, he traveled to Columbus to commit the murders. The following day, 17 hours later, he retrieved his phone, say investigators.

The round trip from Rockford — the site of the hospital where McKee worked — to Columbus is seven hours, meaning that McKee drove at least 14 hours during that 17 hour span, according to investigators’ timeline.
