HOLLAND—The investigation into a March 6 fatal crash near Holland continues, Debbie George, spokeswoman for the city of Suffolk, said Monday.

“It’s really hard to say (when it will be concluded),” George said.

Hollyann Heinrich, 23, of Waverly died in the 1:45 a.m. crash on Glen Haven Drive after being thrown from the truck. Occupants William Davis, 26, of Carrsville and Dustin Bishop, 23, were injured.

Police believe Davis was the driver, which he admitted and then denied.

Police obtained a search warrant in hopes to finding evidence that will tell them who was driving.

Investigators said they found a beer bottle and hard liquor bottle in the truck while executing the search warrant. They took swabs from the steering wheel, the seat headrests and the car’s electronic data recorder.

Police will take the results of their investigation to the commonwealth’s attorney to determine whether or not charges will be filed, George said.
