A man in a standoff with law enforcement fatally shot himself Wednesday on an Andover property where a home burned to the ground, authorities said.

The property in the 300 block of Andover Boulevard also is where Anoka County sheriff's deputies were called in mid-February, when the owner allegedly fired several gunshots and threatened to shoot law enforcement.

The house fire was detected by a passerby about 6:30 a.m. Wednesday, and a SWAT team joined fire personnel in responding to the scene, said Sheriff's Lt. Andy Knotz.

Deputies arrived to find the gunman in a horse trailer with sleeping quarters by a pole building at the back of the property and threatening deputies, according to Knotz.

Fire personnel from several departments "were pulled back for safety" as authorities attempted to make contact with the suspect, Knotz said.

Authorities failed to do so, and around 10 a.m., the man fired one shot and killed himself, Knotz said. The man's identity, or a motive, has yet to be disclosed.

SWAT personnel were called to a house fire in Andover.

Knotz said his office does not believe anyone was in the home while it was burning in what he said was a suspicious fire "under the totality of the circumstances."

The home "burned down to the foundation," he said during the incident's waning moments.

A witness said he spotted horses behind the property. Thor Ranch lists its location at the property's address.

On Feb. 12, deputies were called to the home by a woman who lived there about the property owner threatening to damage a storage pod with a skid loader, according to a criminal complaint filed against the man.

The man ran into the home when deputies arrived and would not follow their orders.

The woman said she received texts from the man that included the threat to "gun down any ... sheriff that comes in here again," the complaint read.

One deputy heard the sound of nine gunshots coming from the home, the complaint continued. The man surrendered four days later. He was charged with felony reckless charge of a firearm and being a felon in possession of a gun stemming from a drunken driving conviction in 2017.
