Aldan Borough Police Chief Ken Coppola says DiSands and Cleaver, who worked for A to U Sewer Services, were found 30 feet down in a sewer hole. Coppola says it appears the victims were overcome by gas fumes, but the medical examiner’s office will perform an autopsy to determine a cause of death.
Hazmat crews are on the scene.
Coppola says four workers were conducting a dye test in the sewers. Two workers were at Magnolia and Sycamore while DiSands and Cleaver were at Rively and Sycamore. When the two men at Magnolia were not getting a response from them, that’s when they learned that the victims had somehow lost consciousness.
By the time first responders were able to reach DiSands and Cleaver, it was too late and they were pronounced dead at the scene.

The police chief added that there is no impact to the community.
The father of one of the victims is a police officer in Delaware County.
“It’s a very heartbreaking situation we got going on here,” Aldan Mayor Carmen Maniaci said.
Nearby residents knew something was wrong when they saw the large police presence.
“I figured because people were outside crying but we were just hoping it was because they got them up and out but it’s sad,” Chantel Tomasella said.
