NORTH RICHLAND HILLS — The search a Sul Ross State University student with deep ties to North Texas has expanded to three counties in West Texas.

News 8 met with Andreana Lynn Doggett, of North Richland Hills. She says she last talked with her best friend the day before she learned from family that Verk was missing.

"We had this saying that we'll be together until we're old and wrinkly," Doggett said. "Thinking that may not be possible really hurts."

On Wednesday night, Doggett went through a box of memories, including pictures and high school letters between her and the missing 22-year-old.

News 8 told Doggett that Verk's boyfriend was considered a person of interest and that his home was part of an active search by investigators. She says she doesn't know much about their relationship.

"They were in a rocky relationship but I didn't really ask much into that," she said.

She describes Verk as a person always ready for adventure, always joking, and always outgoing.

"I know what pain feels like but the unknowing is what is worse," she said.

By Friday the reward for information in Verk's disappearance had increased to $100,000, according to Alpine PD.
