Muskego, WI – A 47-year-old man is charged with reckless homicide after allegedly driving under the influence and crashing his vehicle. Casey Yiannackopoulos is accused of fleeing the scene, leaving his 77-year-old mother behind in the passenger seat.

Witnesses report seeing him running from the crash site on Sunday at approximately 7:15 p.m. First responders encountered the woman, who was the sole occupant of the vehicle, unconscious yet breathing.

Despite emergency efforts, she was pronounced dead at the hospital roughly an hour after rescue.

Surveillance footage captured the vehicle speeding at over 50 mph in a 30 mph zone before it veered off the road. Yiannackopoulos allegedly appeared intoxicated, as noted by witnesses who observed his unsteady movements and strong smell of alcohol.

Witnesses reported he stated he was going to seek help but did not return. After police tracked Yiannackopoulos to his mother’s home, they found him hiding in a crawl space. Officers needed to deploy a drone to locate him under blankets and a plastic bin cover.

When taken into custody, he displayed bloodshot eyes and indicated that he did not know his mother was deceased. A blood draw has been conducted, with the results pending.

Court proceedings reveal Court Commissioner Daniel Rieck expressed disbelief at Yiannackopoulos’ actions, questioning his decision to abandon his mother at the scene of the accident.

Currently, Yiannackopoulos is being held in the Waukesha County Jail on a bond of $750,000. His next court appearance is expected on Thursday.
