Authorities learned that an Oregon convict killed in a police shootout was previously stalking women while driving a van equipped with a "moveable dungeon."
According to the Associated Press, 49-year-old Kelly Swoboda kept notes on about 20 women, rating them and marking down if they were alone at the time of stalking.
"Some of them have license plates, so he has seen them driving and follows them," Portland Police Detective Erik Kammerer testified in court.
Last month, police approached Swoboda after calls were reported about a suspicious van following students outside of a high school. Following an exchange of gunfire, Swoboda was killed.
Following his death, grand jurors met to decide his the killing was justified. The jurors decided it was, the AP said.
Aside from stalking, Swoboda was also the suspect in bank robberies and a kidnapping at a tanning salon near Portland.
The 23-year-old kidnapping victim, who was working alone at the salon, was beaten and forced into a van where here ankles and wrists were bound with duct tape. However, she was able to escape after jumping out of the moving car, suffering a fractured skull and other injuries.
After Swoboda was fatally shot by police, they investigated his van and found chains, ropes, and zip ties. Since the victim hadn't noticed them during the attack, the prosecutor wondered if Swoboda had created the van into a "movable dungeon."
"I'm thinking exactly that one victim got away, and he wasn't going to let the next one get away," said Detective Mary Nunn of the Clackamas County Sheriff's Office, according to a transcript. "Our discussion at my office is that he was coming up with a better way to restrain somebody in his vehicle."
