Alpine police say the reward for information leading to the whereabouts or safe return of a missing West Texas college student has increased to $200,000.

Police announced the increase Monday in the disappearance of Zuzu Verk, a 22-year-old from Fort Worth who is a junior at Sul Ross State University in Alpine.

Police have said her boyfriend, Robert Fabian, has been named a suspect because investigators believe he was the last person with her before she disappeared. No one has been arrested.

Police say Fabian told officers he last saw her on Oct. 12. Police say Fabian went to police two days later to report Verk missing. Police say he's refused to answer police questions since reporting her missing.

Fabian's attorney, Liz Rogers, said she had no comment Monday.
