Fifteen seconds.

That's how long a confrontation by police and an active shooter at a West Omaha Super Target lasted before the gunman was shot and killed, according to the latest update from the Omaha Police Department.

That 15 seconds part of a detailed timeline of the event, released by OPD which finds the first 911 call coming in at 11:59 Tuesday morning, seven minutes later at 12:06 p.m. Omaha Officer Brian Vanderheiden "fired one round from his service handgun" killing 32-year-old Joseph Jones, no one else was hurt.

Police say, Vanderheiden and a state trooper gave "20 loud verbal commands" telling Jones to drop his AR-15 military style assault weapon, which he bought just four days earlier.

We're told Jones said, “Come on!” three times while refusing to drop the rifle, and then told the officers, “I’ll kill you!”

OPD adds that during the incident there were some 250 customers and employees in the store, which reopened yesterday 46 hours after Jones first arrived.
