CLEARLAKE, Calif. – Authorities have taken into custody a Grass Valley man who engaged in an hours-long standoff with law enforcement that included threats to kill himself and others, and necessitated evacuating some nearby homes.

Michael Jacob, 27, was transported to St. Helena Hospital Clear Lake for treatment and examination due to him possibly swallowing glass during the standoff, which began on Wednesday night, according to acting Clearlake Police chief, Lt. Tim Celli.

At approximately 9:16 p.m. Wednesday Clearlake Police Dispatch received a 911 call from a male subject who claimed that he was “Lucifer” and “God,” that it was time to go and that he was going to take people with him, Celli said.

Dispatch believed that the subject was on some sort of narcotic. Sgt. Travis Lenz, along with officers Leonardo Flores, Trevor Franklin and Jared Nixon responded to the man's residence, which Celli said was located in the 3800 block of Manchester Street, to conduct a welfare check on the subject.

When officers arrived at the location, Jacob made claims that he had “guns.” He also made statements that he was going to kill his neighbors and himself, and Celli said Jacob refused to obey officers' requests while making these terrorist threats.

Jacob, who at the time was only identified by the first name of Michael, was in a locked fenced yard. He was delusional and made threats to kill the police officers, the neighbors and then himself. Celli said the officers developed the opinion that he was under the influence of a controlled substance.

Celli said officers attempted to negotiate with Jacob to come out of the fenced and locked yard, however he remained uncooperative and continued to make threats, and then started toward the house. He was ordered to stop by police, but refused.

Sgt. Lenz attempted to stop Jacob from entering the house and possibly arming himself by deploying a Taser at him. The Taser had little effect on Jacob, who ran inside the residence, Celli said.

Jacob used a baseball bat to break out the front windows of the residence while saying he had “guns” and claimed there were other occupants inside the residence. However, Celli said no guns were seen at that point and no other voices or subjects could be heard in the residence.

Celli said Jacob continued threatening police officers and at one point started a chain saw inside the residence. He could be heard yelling and screaming inside the house.

Officers continued to attempt to negotiate with Jacob, who then started throwing large rocks and a baseball bat at the officers out of the front window. Celli said officers continued to try and talk with him to negotiate his surrender but were unsuccessful.

At one point Jacob was observed by officers carrying what appeared to be a rifle. Celli said Jacob placed the rifle in a tactical position near the broken-out front window of the residence and then retreated out of sight.

At that point, once the firearm was seen, officers contacted the Lake County Sheriff’s Office and requested a SWAT response, which Celli said was necessary due to the threats made and the observation of a rifle.

Officers maintained tactical positions and continued to attempt to negotiate with Jacob, who Celli said failed to comply with numerous orders. He could be seen on occasion walking and sitting near the rifle but made no further threats.

As a precautionary measure several adjacent residences were evacuated while officers awaited the sheriff’s office response, Celli said.

Several sheriff’s deputies along with additional officers from Clearlake Police Department arrived on scene and set up a perimeter around the residence, Celli said.

After several hours and continued efforts by law enforcement pleading with him to surrender peacefully, Jacob finally came to the front window. At that point he picked up glass from the broken window and placed shards of glass in his mouth, Celli said.

Celli said Jacob then climbed out the window, where he was met by awaiting police officers and sheriff's deputies.

The rifle Jacob brandished was discovered to be a loaded, high-powered pellet rifle which Celli said was a realistic-looking firearm.

A safety and security sweep of the residence revealed no other occupants inside nor was any other firearms located, Celli said.

As of early Thursday morning, Celli said Jacob remained under observation at the hospital pending his medical clearance for incarceration.

After Jacob's release Celli said it's anticipated that he will be booked into the Lake County Jail.

Celli said charges are being submitted to the Lake County District Attorney’s Office for several felony charges against Jacob including assault with a deadly weapon on a peace officer, brandishing a replica firearm in the presence of law enforcement, resisting law enforcement officers and threatening law enforcement in the performance of their duties.    

The Clearlake Police Department expressed its deep gratitude to the Lake County Sheriff’s Department for its response and assistance in bringing this matter to a safe resolve.
