The reward for a 23-year-old woman missing since Aug. 30 has been raised to $25,000.
Surveillance video from The Shops at Legacy in Plano shows Christina Morris walking with a man identified by family members as a friend of Morris' from high school. The pair can be seen walking through a parking garage, after which Morris was never seen again.
Plano police have said their detectives have questioned that man, as well as several other people, and that no one has emerged as a person of interest or a suspect in Morris' disappearance.
A reward of $10,000 had been offered by Crime Stoppers for information leading to the arrest and indictment of a suspect, if it's determined a crime has occurred. On Monday, that reward was increased by an anonymous donor to $25,000.
Police said Monday that there have been no new developments in the case and that the investigation into Morris' disappearance is still being investigated as a missing person case.
The search for Morris has covered several square miles, and volunteers have worked on foot, on horseback and on ATVs as well as searching by unmanned aircraft.
