Leaked: Suspicious clues that investigators cannot ignore as they investigate the perpetrator’s connection to Monique Tepe’s ex-husband in the Ohio dentist murder case.

For more than 10 days, a manhunt for the suspect in the killings of Spencer and Monique Tepe in their Ohio home with their two young children inside gripped their community and captured national attention.

The ex-husband of Monique Tepe, identified by court records as Michael David McKee, 39, was arrested on two counts of murder on Saturday, an incident report shows.

Spencer Tepe, 37, and Monique Tepe, 39, were found dead with apparent gunshot wounds on December 30 in their upscale house in Columbus. The couple’s two children, ages 4 and 1, were not physically harmed when they were found inside, police said.

The arrest marks a major development in a case which has been shrouded in mystery as police have been reluctant to provide any details about the investigation. Police officials still have not released any information about a possible motive.

Questions about how the killings unfolded and what motivated the attack only intensified Monday when police revealed surveillance footage showing “a person of interest” walking in the alley near the couple’s home in the Weinland Park neighborhood.

The video was taken during the timeframe investigators believe the respected dentist and his wife – a stay-at-home mother – were killed, police said at the time, but did not explain why they were seeking information about that individual.

McKee is in custody in Winnebago County, Illinois, according to inmate records with the sheriff’s office. He is scheduled to appear in court Monday, records show, after police said he was taken into custody “without incident” in Rockford, Illinois.

CNN is working to determine whether McKee has legal representation.

In the days following the killings, a memorial of roses and sunflowers adorned the home where the Tepes had exchanged vows before it became the site of unspeakable tragedy.
