Reports have come back to examine the death of Buffalo Police Officer Craig Lehner who drowned in the Niagara River last October.

After a 5 day, hunt his body was discovered, but the reports show that maybe Lehner was ill-prepared to dive in the river, as his few previous dives were in calm water like the Caribbean where he got his scuba certification.

According to WGRZ, Craig Lehner:

lacked the equipment to verbally communicate with his teammates and would have been limited to making signals with the tether line connecting him to his colleagues onshore. Lehner also did not have a piece of equipment that might have enabled him to free himself in the event his tether became tangled and trapped him under water.

Lehner’s family filed a claim against the City of Buffalo and Buffalo P, which still allows them the opportunity to file a lawsuit against them.
