DES MOINES, Iowa — A 12-hour standoff in Des Moines has come to an end, after a tactical team used tear gas and pepper spray to force the barricaded shooter out of his home. KCCI reports the first shots were fired Saturday morning about 2:45 in the 2700 block of Sampson Street. The station says Des Moines Police say at least two homes on the opposite side of the street from the shooter were hit by gun shots. The suspected shooter, 37-year-old David Harbold, was taken into custody at around 2:45 p.m.”

Crisis negotiators spent more than six hours communicating with Harbold in an attempt to get him to surrender. Eventually, the tactical team gave an ultimatum. Harbold went to the door, still holding a gun, but was arrested by awaiting officers.

Harbold has been charged with two counts of intimidation with a dangerous weapon and one count of interference with official acts with a dangerous weapon. Investigators have not determined a motive for the shooting or whether the homes were specifically targeted.
