Or a street side drug hook-up gone bad.
According to the NY Daily News:
Cops are still hunting for the assailant who stabbed Crown Heights riot figure Lemrick Nelson in the head with an ice pick.
Nelson, who remained in stable condition at Harlem Hospital on Monday, was found lying beside his car on a George Washington Bridge off-ramp in Manhattan at 2 a.m. Sunday.
He was not robbed, so cops think he had a road-rage confrontation with the stabber, who escaped unseen.
The car appeared to have fresh damage, as if it had just been clipped or sideswiped, and the door was open, police said.
Cops also found the ice pick presumably used to stab Nelson, 35.
