Ex-husband arrested in murders of Ohio dentist and his wife after vehicle found near Chicago

ROCKFORD, Ill. -- A Chicago-area discovery has led to charges being filed in the mysterious murders of Ohio dentist Spencer Tepe and his wife, Monique Tepe.

Michael David McKee, Monique's ex-husband whom she divorced in 2017, was arrested in Rockford, Illinois and has been charged in their deaths, court documents obtained by ABC Columbus affiliate WSYX show.

"Today's arrest represents an important step toward justice for Monique and Spencer," the Tepe family said in a statement. "Nothing can undo the devastating loss of two lives taken far too soon, but we are grateful to the City of Columbus Police Department, its investigators, and assisting law
enforcement community whose tireless efforts helped to capture the person involved."

The couple was found shot to death in their home on Dec. 30, Columbus police said. Their two young children were found safe inside.

"This case is definitely disturbing," Police Chief Elaine Bryant told Columbus ABC affiliate WSYX.

Authorities said they believe the couple was killed between 2 a.m. and 5 a.m. on their home's second floor.

Earlier this week, police released video of a person of interest. Police said the video showed an individual walking in an alley near the victims' house during that 2 a.m. to 5 a.m. timeframe.

McKee was arrested after detectives were able to identify a suspect through neighborhood surveillance in Columbus and tracked him to a vehicle. Then, the vehicle was located in Rockford, located about 79 miles northwest of Chicago, court documents showed.

The suspect is being held in custody of the Winnebago County Sheriff's Office. McKee is scheduled to appear in court Monday.

The Tepes' family and friends will come together on Sunday for a celebration of life service.

"We thank the community for the continued support, prayers, and compassion shown throughout this tragedy," the family's statement said. "As the case proceeds, we trust the justice system to hold the person responsible fully accountable.
