Authorities say a 40-year-old California man used a hammer to kill another man before stuffing his body inside a plastic barrel and dumping it in front of this town's city hall.

Prosecutors charged Christopher McNatt on Tuesday with murder with the special allegation of using a hammer in the slaying of 64-year-old Ronald Sauvageau. The Press Democrat of Santa Rosa reports (http://bit.ly/1EYBNhp) that McNatt appeared in court, but he did not enter a plea.

McNatt was due back in court on Thursday.

The blood-stained barrel was covered with a plastic tarp when it was discarded in front of Sonoma's city hall late Friday in California wine country. McNatt was arrested the next day.

Sheriff's officials have not disclosed a possible motive or what, if any, relationship McNatt and Sauvageau had.
