Michael McKee, the vascular surgeon accused of murdering his ex-wife Monique Tepe and her dentist husband Spencer, is facing new charges ahead of his extradition from Illinois to Ohio.
A grand jury in Franklin County voted to indict McKee on four counts of aggravated murder and a single count of aggravated robbery on Friday, Jan. 16, according to court records obtained by PEOPLE.
Prosecutors also allege that McKee used a firearm with a muffler, according to a copy of the grand jury indictment obtained by PEOPLE.
Police said at a press conference earlier this week that a weapon discovered during a search of McKee’s property matched the one believed to have been used in the deaths of Monique and Spencer.

McKee was booked into the Winnebago County Jail on Jan. 10 — nearly two weeks after Monique and Spencer were killed inside their Columbus home on Dec. 30.
The couple was killed just days after their fifth wedding anniversary, and while their two children, ages 4 and 1, were asleep in their bedrooms.
An arrest warrant filed in Franklin County Court said that detectives were “able to identify a suspect through neighborhood video surveillance” and then track that person to a vehicle “which arrived just prior to the homicides and left shortly after the homicides.”
Columbus Police Chief Elaine Bryant said that police also have evidence of McKee being in possession of that car both before and after the killings of his ex and her husband.
Police were able to track McKee’s vehicle to Illinois, where he was taken into custody 450 miles away from the crime scene.
McKee has yet to speak publicly about his arrest, with police telling PEOPLE that he invoked his Fifth Amendment right against self-incrimination when interviewed by detectives.
He also remained silent during his first court appearance on Monday, Jan. 12.
Winnebago County Assistant Public Defender Carrie Poirier informed the judge at the hearing that her client agreed to waive an extradition hearing in the case and intended to enter a plea of not guilty to both counts of aggravated murder with premeditation he had been facing in Ohio prior to this indictment.
McKee and Monique married in 2015 after meeting while attending Ohio State University.
They divorced in 2017 after less than two years of marriage.
