The actor Charlie Sheen recorded a video intended for the former LAPD officer accused of killing three people and writing a long manifesto that indicates he has intentions to kill more.
Sheen, who was praised in Christopher Dorner's manifesto, thanked the suspect for his 'kind words' but asked the man to call him.
"Let's figure out together how to end this thing," Sheen is recorded saying.
The 17-second video was posted Saturday on TMZ. Sheen was dressed in a black shirt and spoke in short, direct sentences. The LAPD did not immediately respond to calls from FoxNews.com about Sheen's message.
Meanwhile, authorities weathered heavy snow and freezing temperatures in the mountains, thousands of heavily armed police remained on the lookout throughout California, Nevada, Arizona and northern Mexico for Dorner apparently bent on revenge and willing to die.
Authorities were hopeful that clearer skies would allow aircraft to help them find Dorner.
"He can be behind every tree," T. Gregory Hall, a retired tactical supervisor for a special emergency response team for the Pennsylvania State Police, said.
"He can try to draw them into an ambush area where he backtracks."
SWAT teams in camouflage scoured the mountains Friday and went door-to-door examining vacant cabins.
Police said officers still were guarding more than 40 people mentioned as targets in a rant they said Dorner posted on Facebook. He vowed to use "every bit of small arms training, demolition, ordnance and survival training I've been given" to bring "warfare" to the LAPD and its families.
