On June 17, 2018 in South Salt Lake, Utah, 44-year-old Abe Martinez entered his grandmother Rose Martinez’s home near 450 E. Stanley Ave and took his elderly grandparents hostage. Family members who could not reach the couple reported an unknown man answered the phone, and police began negotiations after arriving at the residence. Martinez, who had recently been paroled from federal prison and had walked away from a halfway house days earlier, told relatives he intended to harm the couple and became increasingly agitated as a SWAT response was assembled.

A shot was fired from inside the house during the standoff. An immediate action team of three SWAT officers engaged Martinez through a window and fired; Martinez was fatally wounded. Officers found Rose Martinez dead from injuries inflicted by Martinez, and her 71-year-old husband critically injured but alive. Investigators concluded Martinez was solely responsible for his grandmother’s death and the assault on his grandfather; no other suspects were identified and no arrests were made. The Salt Lake County District Attorney’s Office later reviewed the officers’ actions and found them legally justified.

Did anyone in the area see activity near 450 E. Stanley Ave on June 17, 2018 or have information about Martinez’s movements in the days before the standoff?
