A North Carolina state trooper shot and killed a deaf man Thursday night after following the man's car on the highway and into a residential area.

Officials said that around 6:15 p.m., the trooper tried to pull over a Volvo that was speeding on the interstate, but Daniel Harris, 29, would not stop.

Harris then led authorities on a six- to eight-mile pursuit before he must have seen the blue lights, authorities said.

Residents who saw Harris after the shooting said they did not see a weapon on or near him, and the SBI confirmed Friday they had not recovered one.

Some residents in the neighborhood where the shooting happened think that Harris didn't stop right away because of his hearing impairment, WSOC-TV reported.

It's unclear whether Harris knew the trooper was trying to pull him over, or whether the trooper knew Harris was deaf.

The SBI said it is still collecting evidence from the scene, including video from the trooper's in-car cameras.

The Highway Patrol said Saunders is on administrative leave while the investigation is ongoing.

Harris' family raised money for his memorial and cremation on YouCaring.

Friends and neighbors gathered Monday evening to honor Harris. Family members told the crowd at the vigil that they want answers.

Harris' brother, Sam Harris, said his brother was a family man with a big heart.

"He was effervescent, funny, social, people enjoyed being around him, just a very unique man," Sam Harris told WSOC via an interpreter. "It's a nice feeling that you've got a community like this that supports you. It can be overwhelming in a time of grief like this."

Sam Harris hopes the shooting spurs greater awareness between police and the deaf community.

"The police need to become aware of how to communicate with deaf people, what that might look like and how to avoid situations like this from ever happening again," he said.

Trooper Jermaine Saunders has retained an attorney and the SBI is waiting to interview him.
