A 76-year-old man died of apparent natural causes Friday morning at the Lawrence Indoor Aquatic Center, according to Lawrence police.

First responders were dispatched around 8:22 a.m. to 4706 Overland Drive “regarding a medical emergency involving a possible drowning,” Sgt. Amy Rhoads, public affairs officer, said via email around 9:30 a.m. Friday.

“Officers and (Lawrence-Douglas County Fire Medical) arrived on scene and despite first responders’ lifesaving efforts, the patient could not be revived,” Rhoads said via email.
