Twenty-nine-year-old Jacob Cintron of Lodi was being held Sunday in the Bergen County Jail on $125,000 bail.
State police say 43-year-old Wilfredo Pena of the Bronx was driving on Interstate 80 in Saddle Brook when the flat occurred around 2:30 a.m., and he stopped on the side of the road between Exits 62B and 62A.
Pena and a passenger, 28-year-old Segundo Fernandez-Urena of Bayshore, then got out to change the flat. But Cintron allegedly lost control of his car while headed toward Exit 62B and struck Pena's vehicle.
Both Pena and Fernandez-Urena were pronounced dead at the scene.
