Corey E. Moore, 50, Gregg P. Williams, 58, Roderick C. Cota, 63, and Moon John Kim, 52, killed in collision involving commercial truck on Interstate 81 near Sandy Creek, New York

The tanker driver lost control of the truck, jack-knifing and blocking both lanes of the highway. He was about 10 minutes from his Mannsville destination after having delivered milk to Massachusetts, Keller said.

Friends, coworkers and ambulance services around the state showing their grief and support on social media suggested Moore was one of the ambulance company's head mechanics, Williams was an EMT driver, and Cota was both a supervisor and the critical care EMT.

Both organizations are appreciative of the support from everyone who's reached out. Both are also looking to honor the four men the best way they know how.

The three families didn't know each other especially well, but in separate interviews at their homes with Syracuse.com they offered condolences to each other.

Funerals were held Tuesday for two of the three St. Lawrence County men who were killed last week in an accident on Route 81, just south of Sandy Creek.

 Schumer was at RB Lawrence Ambulance in Canton Friday to launch his new effort. He says trucks should be equipped with energy-absorbing underride guards to protect drivers and passengers from crashes.
