Polish man’s cause of death revealed months after vanishing at Chicago party, body pulled from Lake Michigan

The cause of death has been released for a 21-year-old Polish man whose body was pulled from Lake Michigan late last year after he vanished from a party at a Chicago bar, officials said.

Krzysztof Szubert, 21, died by accidental drowning, with ethanol intoxication listed as a contributing factor, FOX32 Chicago reported, citing the Cook County Medical Examiner.

Szubert, 21, was pulled unresponsive from the lake at Oak Street Beach just before 2 a.m. on Dec. 7, Chicago police previously said. He was rushed to Northwestern Hospital, where he was pronounced dead.

Police said Szubert appeared to have a laceration to the right side of his head and had launched an investigation into his death, the station reported at the time.
