Five-hour standoff in south Boise ends with arrest of 26-year-old man on aggravated assault and drug charges

Justin T. Larson is charged with resisting arrest in connection with a five-hour long standoff in a south Boise neighborhood Monday night that began earlier in the day when he threatened a woman with a gun.

Larson is also charged with felony counts of aggravated assault, unlawful possession of a weapon by a convicted felon, and three counts of possession of a controlled substance in connection with the case.

The incident began shortly before 3 p.m. Monday when a woman told deputies Larson pointed a handgun at her in the driveway of a home in the 3900 block of W. Leland Way and threatened to hurt her.

The woman said she left before anything else happened.

Deputies began searching for Larson and determined he was still inside the Leland Way home. They attempted to contact him but he refused to answer.

Deputies then went to the home and set up a perimeter once they determined Larson was the only person inside.

Investigators then activated the Ada Metro SWAT team, who began arriving at the home shortly after 7 p.m. The SWAT team brought their MRAP armored vehicle out to the scene as a precaution.

Once the SWAT team set up around the home, they used loudspeakers to try to get Larson to come out. They also took a K9 dog to the door and asked him to leave, but he did not respond.

With the permission of the homeowner, SWAT team members opened the door and sent their robot camera in to search inside.  SWAT team members then went inside the home and found Larson, who was hiding in the attic and refused to come out.

Deputies eventually sent a K9 dog into the attic to get Larson to leave. That’s when Larson fell from the attic and through the ceiling on to the ground, where he was taken into custody.

The standoff ended just before midnight.

Deputies found a computer bag in the house belonging to Larson that had small amounts of cocaine, methamphetamine, heroin, and marijuana inside — along with a 9mm handgun he told investigators he had in his waistband earlier in the day.

Larson was then booked into the jail, where he was also arrested on two active warrants for felony probation violations.

The 26-year-old Larson is set to make his initial court appearance Tuesday afternoon.

Deputies were in contact with the people in the homes near the standoff and asked those residents to shelter in place until it was over.
