ABC7 followed homicide detectives for hours on Tuesday as they looked for the suspected teenage killers. Police searched hotels, questioned people on the street, and followed up on every single lead.
San Francisco homicide detectives are trying to retrace the steps of two teenaged murder suspects. Steven "Boston" Colver, 19, and his girlfriend, Tylar Witt, 14, may be in San Francisco. Their car was towed from a spot on O'Farrell Street, just a few hours after El Dorado County investigators found Joanne Witt murdered inside her own home.
"Everything that was discovered at the house, and some other things I can't go into detail about, lead us to believe both of these subjects are directly involved in the murder of this victim," said Sgt. Jim Byers with the El Dorado County Sheriff's Department.
El Dorado County investigators are saying very little about how or why the victim died. Only, that it was violent.
"I'm shocked. We'd see the daughter walking home from school, she'd waive. It seemed like a nice family," said Mindy Takeuchi, the victim's neighbor.
Colver has been living with his girlfriend's family. Detectives believe the two killed Joanne Witt on Friday. That night, the two checked into a Holiday Inn on Van Ness. Late Tuesday, San Francisco police left the hotel after searching it for hours.
"She's got black hair now. She's 14, he's 19, and they're a couple," said a San Francisco detective.
Meantime, the search in the Tenderloin continued. Tayler Witt is believed to now have short, black hair.
Regardless of the description, the answer is still the same. No one can solidly say they've seen these two teenagers from El Dorado County.
Investigators are not sure why the suspects even came to San Francisco - neither has any ties to the city.
