TROY — A city man fleeing police in a National Grid truck early Wednesday crashed into the Hudson River, police said. The body of Joshua Evans, 21, was pulled from the water around daybreak.

Evans was not a National Grid employee, Troy police Capt. Daniel DeWolf said.

Three heavy-duty tow trucks pulled the dump truck out of the water about 6:30 a.m. at the federal lock off Bond Street in the city's Lansingburgh section.

Troy police responded about 1 a.m. to the Smith Street National Grid lot after Evans hit a 22 Douw St. home by driving into the fence separating the property from the lot. An occupant of the home was trapped for a short time inside a bedroom but was not injured, DeWolf said.

Evans was circling the National Grid lot when police arrived, DeWolf said. Officers on foot chased the driver, flagging him down and ordering him to stop.

"One of the officers was running next to the driver and he said he didn't even acknowledge him," DeWold said. The man fled, driving the truck through a National Grid fence into the federal lock complex next door. "He really took off within the property," DeWolf said. After driving a short way, the truck plunged into the Hudson River.

Officers rushed to render aid but Evans did not surface. State Police divers later recovered his body from the truck, DeWolf said.

National Grid spokesman Patrick Stella said the truck was stolen from National Grid's Smith Avenue facility, but added few details due to ongoing investigations.

"At this time, we continue to offer our full cooperation with the authorities on their investigations as well as conducting our own," Stella said.

Police are investigating how the man got into the complex and where he got the truck's keys, DeWolf said. "It's pretty secure," he said. "There's barbed wire around the top of the fencing and the gates are locked."

Investigators are unsure why the man acted as he did. An autopsy will be performed Wednesday, DeWolf said.

The truck never left the National Grid lot and federal lock complex during the incident.

"Thank God he didn't get out onto the street," DeWolf said. "But it's still tragic, whatever his reasoning was."

Investigators were documenting fence and lawn damage early Wednesday.

Al Bates, the supervisor at the Troy federal lock compound, said he woke at 1:30 a.m. to calls from Troy police officers who could not get inside the compound. DeWolf said an officer found a security guard, who opened the gates.

Federal Lock 8 is temporarily closed pending the investigation, clean-up and inspection, the Army Corps of Engineers said. It will reopen later in the day but there is no specific timeline.

The damaged truck has been stored inside a company garage near the accident site.

Officials from the state Department of Environmental Conservation were on scene with National Grid employees and Troy police. Besides the gas and oil in the vehicle, there were no other hazardous materials spilled in the Hudson River, DeWolf said.

The Red Cross has provided two adult residents of the Douw Street home with food, clothing and lodging. The occupants declined to comment.
