Here's how it happened, as we reported in our previous coverage.
At 9:05 a.m. on January 24, 2016, a Jefferson County Sheriff's Office dispatcher was alerted to what the JCSO characterized as "a disturbance" on the 5400 block of South Taft Court. Immediately thereafter, more 911 callers spoke about shots fired.
Deputies rushed to the scene, where they discovered that an SUV driven by a gravely injured man later identified as David Martinez, 38, had smashed into a home near where the shooting had taken place. Martinez subsequently died of his wounds.

At that point, the pair moved on to their next target: Mott's SUV. But before they could spirit the ride away, Mott freed himself, grabbed his gun, headed to the front porch and yelled at the men to stop. Martinez is said to have reacted by producing a gun of his own, and Mott opened fire. The aforementioned crash followed.
In the meantime, Mascarenas fled the scene in a gold 1990s-era Mustang. But it didn't take long for the JCSO to learn his name, thanks to his use of Mott's credit cards — an act very much in keeping with the many offenses on his rap sheet, which dated back 35 years and filled seventeen pages. His convictions included burglary, drug possession and driving under the influence.
At the time of his unwelcome visit to Mott's home, Mascarenas also had an active warrant in his name for first-degree burglary, aggravated robbery and identity theft.
Two days later, Mascarenas was taken into custody — and the following month, Mott was officially cleared by prosecutors under Colorado's Make My Day law.
In a statement announcing that Mott wouldn't be charged, First Judicial District DA Pete Weir said, “It is standard procedure for law enforcement to conduct an investigation into any death resulting from a gunshot wound. The Jefferson County Sheriff’s Office did a very thorough investigation in this case. Following their presentation of the evidence regarding the shooting of Mr. Martinez, the decision was made that criminal charges were not warranted.”
Earlier this month, Mascarenas pleaded guilty to aggravated robbery, first-degree burglary, motor vehicle theft, menacing, identity theft and false imprisonment. At a December 9 hearing, he's expected to be sentenced to between 32 and 40 years in prison.
