A couple was found dead in the underground parking garage of their Buffalo Grove condo complex on Nov. 17.
Buffalo Grove police have not determined a motive for the shooting, they believe Anatoliy Ermak, 64, is responsible for the attack that left his ex-wife, Nataliya Ermak, 55, and her husband, Roman Frid, 69, dead.
Security video shows Ermak entering through an open garage door and briefly speaking to the couple near their car before firing multiple shots at close range, police said. He left though a side door.
Ermak is wanted on two counts of first-degree murder in connection to the attack, Buffalo police said.
Police said he has an active passport and his whereabouts are unknown.
