A 58-year-old Indianapolis man died Sunday after going missing for just five to ten minutes while boating with a group near Allen’s Creek at Monroe Lake, according to Indiana Conservation Officers. Jeffrey Cox disappeared from view while the vessel was anchored and was later found unresponsive in the water near the boat, not wearing a personal flotation device.
Emergency responders were dispatched to the lake area near Allen’s Creek on Sunday after receiving reports of an unconscious person pulled from the water, according to WBIW. First responders and bystanders attempted CPR and other lifesaving measures at the scene, but resuscitation efforts were ultimately unsuccessful. Cox was pronounced deceased at approximately 4:55 p.m.
Multi-Agency Response at the Scene
Indiana University Health and the Monroe Fire Protection District both assisted alongside conservation officers as crews worked to save Cox. Search and rescue operations on Monroe Lake typically draw on this kind of coordinated response, with the Indiana Department of Natural Resources Law Enforcement Division, fire district personnel, and medical crews from IU Health all playing roles during water emergencies, per The Bloomingtonian. The Indiana Department of Natural Resources Law Enforcement Division is now investigating the incident, and Indiana Conservation Officers are handling the broader investigation into Cox’s death in Monroe County.
Monroe Lake sits roughly 10 miles southeast of Bloomington and about 58 miles southwest of downtown Indianapolis, making it a common weekend destination for boaters traveling down from Marion County, a distance that helps explain why an Indianapolis resident was out on the water. The reservoir is Indiana’s largest inland body of water, spanning approximately 10,750 surface acres across Monroe and Brown counties, after the U.S. Army Corps of Engineers dammed Salt Creek to create it in 1965.
A Troubling Pattern at Allen’s Creek
Cox’s death is not the first tragedy tied to this stretch of shoreline. Almost exactly one year earlier, on August 17, 2025, 27-year-old swimmer Keynner Lugo went missing in the same Allen’s Creek area after struggling to swim to shore from a boat; his body was recovered two days later by conservation officers, according to WTHR. In June 2025, 35-year-old Zacharia Sweet drowned near the same cove after falling off an inner tube without a life jacket, an incident that led prosecutors to charge the boat’s driver with operating a motorboat while intoxicated resulting in death…
