A man was killed and two others shot during a violent weekend in Clearlake that also included a double stabbing, police said.

Four Clearlake residents were in custody Monday, suspected in the shooting that apparently killed and injured uninvolved bystanders, Clearlake Police Sgt. Nick Bennett said.

The shooting apparently stemmed from an argument at a shopping center between a man and some of the suspects, Bennett said.

The suspects reportedly followed the man they argued with to a rural neighborhood where the shooting occurred near Gardner and 19th avenues.

Police were called to the area at 12:53 p.m. They found a dead man, an injured man with an elbow wound and a woman with a grazing wound to her stomach. They were taken to area hospitals.

They apparently weren't involved in the incident at the shopping center.

"They didn't even shoot the guy they were after," Bennett said.

By Sunday afternoon Clearlake detectives had identified and arrested Clearlake residents Joshua Beavers, 24, on suspicion of murder and attempted murder and Orlando Esquivel, 48, on suspicion of conspiracy, jail records show.

By late Monday morning they'd arrested two more suspected of participating in the homicide, Brenden Alicea, 26, and Esquivel's wife, Angel Esquivel, 50, Bennett said. They were apparently in a van at the time of the shooting and tried to conceal weapons and the other people involved, Bennett said.

All four suspects were being held at the Lake County Jail in lieu of $1 million bail.

None of the victim's names had been released Monday.

Earlier Sunday Clearlake officers arrested a local resident they suspected stabbed two people.

Suspect John Dalmolin, 42, had gone to a Grant Drive home to see an ex-girlfriend and got into a fight, police said.

Robert Logue, 40, and Samuel Farnan, 19, suffered stab wounds and were taken to St. Helena Hospital in Clearlake, police said.

Farnan then was transferred to Santa Rosa Memorial Hospital because of his injuries, according to police.

Dalmolin was arrested on suspicion of assault with a deadly weapon, hit and run and an outstanding warrant. He was booked into the Lake County Jail with bail at $30,000.
