Update 4:26 p.m.: Los Angeles mayor Antonio Villaraigosa announced a $1 million reward for any information that leads to Dorner's arrest. "Our dedication to catching this killer remains steadfast," he said at a press conference. Police are still searching the are around Big Bear where his charred SUV was located earlier this week.

Original: The manhunt for Chris Dorner, the ex-cop who killed three people, is still ongoing. No one knows where he is, or where he wil show up next. But one of the lines in his haunting manifesto has police worried he could target tonight's Grammy ceremony for an attack.

CBS senior correspondant John Miller is a former LAPD bureau chief. He reports some of his former colleagues are very anxious about Sunday night's proceedings because of a particular line in Dorner's manifesto, and the potential of a police force spread thin.

Dorner's manifesto promised to target "command posts" like the one that will be set up for Sunday's grammy award show. "I will mitigate all risks, threats and hazards. I assure you that Incident Command Posts will be target rich environments," Dorner promised.

These "command posts" are small, major police posts set up to handle big events like Sunday's award ceremony. "There will be the Grammys Sunday in Los Angeles, where you will have a major police command post," Miller explained. "I've spoken with people there and their problems are very interesting. One problem is, can they get enough cops to police the Grammys, when they have had everyone out deployed on this? People are being called in on days off, overtime and such. But they believe he's shifted from being the hunter to being the hunted."
