A 24-year-old man working on an addition to a boathouse in Pennsylvania drowned after receiving an electrical shock last month. He was found unresponsive in the water by the homeowner.

An engineer with Barry Isett & Associates, Harvey Lake Borough’s third-party building code service, found the electrical wiring in the new structure was installed incorrectly, which caused the electrical shock Watkins received from a boat lift according to a report from The Times Leader.

The police chief said that a stop-work order was now in place for this property. Violations were found at the site, he said.

OSHA is investigating.
