BOSTON -- A man accused of killing a special needs teacher in a hit-and-run crash while high on heroin was ordered held on bail at his arraignment in Quincy on Monday.

Police: High Driver Kills Special Needs Teacher

Eric Lum, 28, of Randolph, pleaded not guilty in Quincy District Court to several charges, including motor vehicle homicide, operating under the influence of drugs and larceny of a motor vehicle. He was ordered held on $100,000 bail.

Lum was driving his mother's SUV just before midnight on Sunday when it crossed the center line on Route 28 in Milton, slamming into a car being driven by Alison Regan, 25.

Police said after the crash, Lum fled into the nearby woods and called his mother to pick him up. Regan was pronounced dead at a local hospital.

Lum, who prosecutors said has a long criminal record, had a suspended license at the time of the crash.

"(His record) is eight pages long. He has 21 contacts with the criminal justice system, 15 defaults, seven violations of probation. He has two prior convictions for leaving the scene and six convictions for driving with a suspended license," prosecutor Emily Nesson said.

Police said they found drug paraphernalia in the front seat of Lum's vehicle.

"He is a good kid. He had a mistake," Lum's grandmother told reporters as she left the court

"It is an old cliché. He is a good kid. He struggled with heroin addiction. We got him help before. He seemed to be on the road to recovery. Obviously, it is a lapse he has gone through with horrendous results," Lum's father Braun Lum said.

Regan, a 2002 graduate of Milton High School, taught autistic children at the Boston Higashi School in Randolph.

"Alison brought beauty, kindness, compassion, positive energy and a special brightness to one and all. She will be dearly missed and lovingly remembered most especially by her students," the school said in a statement.

Regan would have turned 26 on Friday.

The driver of a third vehicle involved in the crash was unhurt.
