BIG BEAR LAKE, Calif. (KABC) -- As the manhunt continues Friday for suspected cop killer Christopher Dorner, there is concern that he might be leading law enforcement on a wild goose chase.
Authorities say Dorner may be utilizing his knowledge of both police and military tactics to evade capture.
San Bernardino County Sheriff's Spokeswoman Cindy Bachman held a 4 p.m. PT news conference from the command station. She said the search would continue overnight Friday and into Saturday.
Bachman said foot tracks were investigated, including ski tracks "associated with" the foot tracks, and were determined not to belong to Dorner.
A cabin six miles from the scene was found with its door kicked in. Authorities determined it was old damage and that there was no recent activity there.
Bachman confirmed that Dorner's mother owns property in Arrowbear, about 35 miles away from the scene. The property is undeveloped and has no structures built on it. Authorities investigated and cleared that site.
Bachman said at least 12 2-man units would be added to regular police patrols in the Big Bear area overnight.
The sheriff's command station was moved from a golf course to the Big Bear sheriff's station on Summit Boulevard. The golf course was closer to the site of where Dorner's burning truck was found Thursday.
