Neither drugs nor alcohol were factors in the July 14 drowning death of a 22-year-old Plymouth man, according to toxicology results released by the Marshall County Coroner’s office. Valentin Sirghi, 22, was swimming with a friend near the public beach at Lake Maxinkuckee when he went under water. Rescue teams searched the area for about an hour before they found his body. Sirghi was pronounced dead at St. Joseph Memorial Hospital in Plymouth. Final autopsy results are pending, but preliminary indications are that Sirghi died as a result of asphyxiation due to drowning.
