On a November evening in Tucson, officers responded to a shooting call in the 7100 block of East Speedway Boulevard and found 41-year-old Mary Blankenship with a gunshot wound to her back. She was rushed to Banner University Medical Center with life-threatening injuries and died on the afternoon of November 26, 2017.

Mary’s fiancée, 35-year-old Ryan Secor, initially told police that he and Mary had been approached by several unknown men who asked for cigarettes, and that he heard a loud noise before seeing the men flee and discovering Mary had been shot. Investigators recovered a shell casing and a bullet at the scene. The next morning detectives found Secor nearby, sleeping and in possession of a handgun whose caliber matched the evidence. In a later interview Secor admitted there had been no other men and that he had shot Mary, saying the shooting was an accident. He was arrested and initially booked on felony aggravated assault; after Mary’s death the charge was amended to include second-degree murder.

Are there anyone who knew Mary or who was in that neighborhood that night who can shed light on what happened?
