Concord police are asking for the public's help in the ongoing investigation into the death of a homeless man whose wheelchair was hit by a car on Interstate 393 in New Hampshire.
Sixty-two-year-old Gene Parker died several days after the Jan. 28 crash in the eastbound shoulder of the highway, where people often walk when the sidewalk is covered in snow or ice.
His death has sparked debate over who should plow that stretch of state-owned sidewalk. The state says it doesn't maintain sidewalks, while the city says it would be trespassing if it tried to maintain state-owned property.
On Wednesday, Concord police said they are looking for several people who stopped to help Parker after the crash, including someone who identified himself as a doctor.
