A Suffolk grand jury on Monday handed down sealed indictments against a 27-year-old Carrsville man who was involved in a deadly crash in March.

The documents became public Tuesday when police arrested William Byrum Davis on charges of aggravated involuntary manslaughter, assault by maiming while driving while intoxicated, first-offense driving while intoxicated and reckless driving.

Police say Davis was the driver in a March 6 crash on Glen Haven Drive, near Holland, that killed 23-year-old Hollyann Heinrich, of Waverly, and injured 23-year-old Dustin Bishop.

According to police, the 2005 Chevrolet pickup left the roadway to the right, continued into the ditch, hit a culvert and traveled through a yard, where it flipped two and a half times. Davis initially admitted to being the driver, police said, but then recanted that statement and said he did not know who was driving.

According to a search warrant, police found a Bud Light beer bottle and a Henry McKenna liquor bottle in the truck. Several bottles of Bud Light also were strewn about the scene of the wreck, the search warrant said.

Investigators also took swabs from the steering wheel and all of the headrests in an effort to determine who was driving.

The victim’s father, Steven Heinrich, visited Suffolk in November to find out why the investigation had dragged on for more than eight months. A city spokeswoman said the case had gotten held up on the desk of a sergeant who was supposed to review it. Heinrich’s visit speeded up the process, and it was sent to the Commonwealth’s Attorney’s office that day.

That office did further investigation and presented evidence to the grand jury on Monday, Commonwealth’s Attorney C. Phillips Ferguson said Wednesday.

“I’m glad about what transpired,” Heinrich said on Thursday. “I don’t think somebody should get away with that.”

“I was very happy about it,” said Hollyann Heinrich’s best friend, Ashley Zoder. “I’m just in shock right now. I didn’t think it was going to happen at all for a while.”

Davis’ first court date is set for Feb. 22.
