Illinois surgeon indicted for double homicide of ex-wife and husband
Domestic Violence
The case involves a divorced couple where the ex-husband allegedly killed his ex-wife and her new husband. The violence appears motivated by jealousy and domestic conflict following the divorce. The use of a firearm suppressor and the absence of forced entry suggest premeditation and targeted aggression.

A firearm matching evidence at the scene was found at his residence. No forced entry or weapon was found at the victims' home. The couple's children and dog were unharmed.

High risk due to prior divorce, access to firearms, and escalation to lethal violence.
Divorce and ongoing domestic conflict can escalate to lethal violence, especially when firearms are accessible. Community tips and video evidence were crucial in identifying and arresting the suspect. The absence of forced entry highlights the importance of considering known suspects with access.
The divorce and ongoing conflict between McKee and Monique Tepe were key early signals. McKee's access to firearms and proximity to the victims were critical.
Video footage of McKee near the home, vehicle tracking, and matching firearm evidence connected the suspect to the crime.
Video surveillance, vehicle location data, and ballistic matching of the firearm found at McKee's residence were strongest.
