Police found both men on the ground, not breathing, at the 17-acre Washington Pond condominium complex off Pascack Road and Linwood Avenue just after 8 a.m. Dec. 11
CPR was conducted on both at the scene before they were rushed to The Valley Hospital.
The men "appeared to be overcome by the fumes of a running lawnmower in the trailer," Detective Heather Castronova said at the time.
One died soon after.
His co-worker held on until last week, when he was taken off life support and his organs were harvested, sources told Daily Voice.
OSHA responded to last month's incident -- along with township first responders and the Bergen County Sheriff's Bureau of Criminal Identification, which collected evidence.
The trailer belongs to AJR Landscaping of Cresskill.
