There is new information about a missing Colorado Springs woman. Police now confirm that the Dodge Durango that was involved in a high-speed chase does, in fact, belong to 55-year-old Beverly Mountz. And her son, Nick, was at the wheel.

She disappeared Tuesday night and family members think Beverly's son had something to do with it.

Right now, police won't call Robert “Nick” Mountz a suspect in her disappearance. But they do call him a “person of interest.” And while detectives did interview Nick in a New Mexico jail, they are being very tight lipped about what they learned.

The Mountz family waits anxiously for any news on the investigation into Beverly's disappearance. But police are releasing very little information about the case.

What we have learned are more details on the high-speed chase on Wednesday. "It's our understanding that a couple driving southbound on I-25 heard a description of the vehicle being aired on the local radio station, contacted the State Patrol and advised them that they were following this vehicle southbound on I-25," says Colorado Springs Police spokesperson Lt. Rafael Cintron.

The vehicle, a 1999 Silver Dodge Durango, was driven by the missing woman's son, Nick Mountz. The State Patrol says the chase lasted 20 minutes and covered 35 miles--- at times reaching speeds of 100 miles an hour. And police confirm, the Durango belongs to Beverly Mountz.

After the chase, Nick Mountz gave up peacefully just north of Raton, New Mexico. “He is currently in the custody of the New Mexico State Police on unrelated escape charges and also traffic violations," says Cintron.

Police in Colorado Springs were immediately notified of the arrest. "Detectives from our Major Crimes Unit responded to New Mexico yesterday evening to interview Robert Mountz about the disappearance of his mother," says Cintron.

Police will also not comment on what, if anything, was found inside the vehicle.
