A 61-year-old Savin Hill man was dragged to his death Sunday night as he pleaded with the driver of the vehicle that struck him to stop. ''Oh, my God, please stop,'' a witness heard Richard A. Miller shout as he clung to the passenger side of the red pickup truck or SUV that dragged him for several hundred feet down Dorchester Avenue.

Miller, a Vietnam War veteran and longtime advocate for Cambodian and Vietnamese refugees, fell to the pavement and was run over. The driver sped away without ever slowing, police said.

''The poor fellow. He kept yelling, `Stop, stop, stop,' '' said Bill Kelly, the owner of the Dorchester Tara Pub on Dorchester Avenue, who said he was checking a patron's identification at the door around 11:45 p.m. when he heard frantic yells.

Kelly, who estimated that the vehicle was traveling at least 50 miles per hour, rushed over to Miller, but he was already dead.

''This is something you see in the movies,'' Kelly said. ''I saw this flash of red and the next thing I see he's rolling on the ground and his head is all over the road.''
