UPDATE: Police investigators remove 1,500 pot plants from Healdsburg fatal shooting scene

Sonoma County Sheriff's investigators removed "in excess of 1,500 marijuana plants" Wednesday from a house north of Healdsburg in the wake of a fatal shooting late Tuesday night.

Sonoma County Sheriff's Lt. Dennis O'Leary said the "substantial" number of pot plants were taken from an outbuilding at the home in the 300 block of Alexander Valley Road and from a "grow room" inside the house.

A Cloverdale man has been arrested on suspicion of fatally shooting his sister's boyfriend  at the home, which all three of them once shared, O'Leary said.

The victim, 29-year-old Timothy Neuer, was shot at the Alexander Valley Road home that he shared with his girlfriend, Amanda Miller,  O'Leary said.

Miller's brother, 29-year-old Jarrod Joseph Miller, had recently moved out of the house, O'Leary said. He was arrested by Windsor police on Old Redwood Highway north of Limerick Lane later Tuesday night.

Sonoma County Jail staff said Miller has been charged with murder. He is scheduled to be arraigned on the charge at 1:30 p.m. Thursday in Sonoma County Superior Court.

O'Leary said Miller was being held without bail. A bail hearing could be scheduled later this week or next week, he said.

"We don't have a motive at this time," O'Leary said.

On Wednesday, sheriff's investigators gathered behind crime scene tape strung across the driveway at the two-story yellow house with green trim at the property, just past the Alexander Valley Cellars winery.

A Geyserville fire truck arrived shortly before 2 p.m., pulling in at a detached shop or garage in the rear of the lot. Within about 10 minutes, a flatbed truck emerged and exited the property, loaded with what is now confirmed as 1,500 marijuana plants covered with brown cloth.

O'Leary said police found the "substantial" indoor marijuana grow in the house where the shooting happened. He said investigators don't believe the killing was related to the marijuana grow.

Neighbor Wes Magnuson said he had never met the three occupants of the home, but he assumed they were tenants on the property. He said the owner, who could not be reached for comment,  was a local resident on Soda Rock Lane.

He said he didn't hear anything last night and that he had not been questioned by police.

"When I woke up this morning, I saw police cars there," said Magnuson, who lives across Alexander Valley Road from the house where the shooting occurred. "Then my daughter said, 'They've got crime scene tape up.'"

Magnuson said the five-acre property has had numerous changes in ownership over the years, but that there's never been any problems there before.

"I've lived here all my life," he said.

According to a Bay City News report, Amanda Miller told sheriff's deputies her brother was at the house Tuesday night, O'Leary said.

"She said there was no argument. Everything seemed fine until he started shooting," O' Leary said.

Amanda Miller reported the shooting to the sheriff's office around 11:20 p.m., Lt. Steve Brown said.

She left the house and closed the front door after the shooting, and was outside on the property when deputies arrived, O' Leary said.

Deputies broke down the locked front door and found Neuer dead on the floor, Brown said. He had been shot several times.

Miller told deputies her brother had left with a handgun in a white Chevrolet Suburban, Brown said.

Windsor police officers spotted the Suburban traveling south on Old Redwood Highway north of Limerick Lane and arrested Miller, Brown said.

He told the officers he had thrown the gun out the car window just before he was pulled over, Brown said.

A California Highway Patrol officer found the small-caliber handgun in a vineyard about 500 yards north of where Miller was stopped, Brown said.
