On Tape: Cop Berates Victim, 13

(CBS)  A parking lot surveillance tape at a Minnesota mall captures the final moments of a 13-year-old girl's kidnapping.

"He grabbed me around the waist by gun point and brought me into the car," the girl says.

She was sexually molested and then dropped off at a mall.

But as CBS News Correspondent Mika Brzezinski reports, the memory that haunts her even more is what happened when she went to the police for help.

A stunning police video shows that White Bear Lake Detective Tim Stevenson, a 12-year veteran, appears to have decided the girl was lying even before he conducted the interview.

"I'm talking to you alright, and you keep lying and lying and lying and lying," Stevenson says in the tape. "I'm watching the whole thing. You never showed up there. You were never there. You never got dropped off there."

"It's time to be a woman and step up and take responsibility of what you have done," said Stevenson.

Apparently, he didn't watch the whole thing. With some detective work of their own, the girl's parents combed through the entire surveillance tape and discovered her story was true.

But by then - more than a week later - the suspect was long gone and the psychological damage of the interrogation was done.

Behind closed doors, anything goes between police and child victims. There are no national regulations for how these interviews are conducted. Training is often on the job. In many cases, young, vulnerable and often traumatized children are alone with detectives who can use whatever tactics they want.

Victor Veith, is the director of the National Child Protection Training Center. Through role-playing with actors, his agency teaches law enforcement how to gather information from young victims of sexual assault.

Veith says most police are more accustomed to interrogating adult suspects than interviewing juvenile victims.

"We need to get to the point in this country where the vast majority of interviews are at least conducted sensitively and competently and when errors are made they don't re-traumatize the child," said Veith.

Yet only three states require videotaping of interviews and even that did nothing to make this young girl's experience any less traumatic.

"It's time to be a woman and step up and take responsibility of what you have done," said stevenson.

Nobody from the White Bear Lake police department would talk to us citing litigation by the girl's family. Stevenson was removed from the case but two years later, he's still on the job and the attacker remains on the loose.
