Westmont man charged with killing dad, fleeing police

A Westmont man with a history of mental illness was ordered held Thursday without bond in the fatal stabbing of his father two months ago.

Prosecutors charged Rostyslav Demtsyo, 28, with first-degree murder. Handcuffed and seated in a wheelchair, he appeared briefly in court as prosecutors sought a psychological evaluation.

DuPage Circuit Judge Kathryn Creswell may rule on that request Tuesday.

At 9:15 p.m. Nov. 19, police rushed to an altercation between Demtsyo and his 53-year-old father, Oleg, outside their home on the 200 block of North Wilmette Avenue in Westmont.

The first police officer arrived within minutes, but authorities said the son had fled. The elder Demtsyo suffered more than 30 stab wounds. He was pronounced dead at Advocate Good Samaritan Hospital in Downers Grove.

Police caught up with the younger Demtsyo's 2006 Dodge Stratus after spotting him traveling south of Cass Avenue near 55th Street. Shortly afterward, Demtsyo struck a southbound SUV on Cass Avenue at 73rd Street. The SUV hit a northbound motorist. The Stratus then crashed into a tree.

Rescuers rushed five people from the three cars, including Demtsyo, to area hospitals. One of the motorists recently filed a lawsuit seeking damages against Demtsyo, according to court records.

Initially, Demtsyo's injuries were considered severe. He was put into a drug-induced coma to stabilize him. An arrest warrant was issued Tuesday, and he was released from the hospital Wednesday.

It was his mother, Irina, who called 911 Nov. 19 after witnessing the violent dispute between her son and husband in the family driveway.

Authorities said she told them her son, who has a history of mental illness and had run out of his medication, attacked her husband after growing increasingly paranoid and delusional.

Afterward, he demanded she give him his car keys. Authorities said he threatened his mother, but did not physically harm her.
