Two Santa Rosa men were arrested Monday afternoon in connection with a week-old home invasion robbery involving the theft of marijuana from a northwest Santa Rosa home, police said.

William Kammerer, 23, and William Pope Jr., 24, are suspected of assaulting another man after forcing their way into his Autumn Walk Drive home near San Miguel and Waltzer Roads on Feb. 5, police Sgt. Dave Linscomb said.

Kammerer, an ex-felon, reportedly held the victim at gunpoint while Pope rifled through the house and took a large quantity of manicured marijuana, police said.

The victim, whose name has not been released, was beaten up but not seriously injured, Linscomb said. A second man who was visiting him at the time of the home invasion was not hurt, he said.

In addition to the unknown quantity of marijuana stolen, police found several pounds of pot at the victim's residence, perhaps left behind because the suspects hadn't found it, as well as drug paraphernalia, police said.

Investigators are scrutinizing the victim's activities to determine if he was running a drug-dealing operation, Linscomb said.

The home invasion occurred the same day that three men were gunned down in a rural Forestville home during a suspected marijuana sale that has highlighted the frequent links between criminal violence and marijuana.

The Santa Rosa robbery occurred in broad daylight, around 3:30 p.m., and the culprits left soon afterward, police said. But the victim did not immediately report the incident to police, who did not make it public for investigative reasons, Linscomb said.

Police had leads connecting Kammerer to the case fairly early, and on Monday served a search warrant at his Burt Street home, where they recovered more than 100 pounds of dried marijuana, drug paraphernalia and a loaded firearm, Linscomb said.

Kammerer, who has a previous robbery on his record, was arrested on suspicion of robbery. Pope was arrested and booked on suspicion of robbery at his home on nearby Santa Rosa Avenue, Linscomb said. Both were released from jail after posting bail Monday night, jail personnel said.

Both men are to make their first court appearances Friday. Authorities reportedly are seeking additional charges again Kammerer for unlawful possession of a handgun by an ex-felon and suspected possession of marijuana for sale, police said.

Anyone with information about the case is asked to call the police department's violent crimes investigation team at 543-3590.
