On the morning of July 14, 2021, 19-year-old Dean Ryan Marcishak was found fatally shot in the parking lot of the Green Leaf at Broadway apartment complex on Tucson’s east side. Responders pronounced him dead at the scene after the discovery around 6 a.m.

Investigators determined the shooting occurred during an attempted armed robbery. Tucson police identified two teenage suspects and arrested a 16-year-old, Brian Lann, after evidence tied him to the crime in a nearby apartment. A 15-year-old, Samuel Salisbury Jones, was later taken into custody by Tucson SWAT and K9 officers.

Both teenagers were charged with first-degree murder; Lann also faced an attempted armed robbery charge, and Jones was charged with two counts of attempted armed robbery and a felony probation violation. Both were booked into the Pima County Adult Detention Center. If anyone knew Dean or has information about the events that morning, please come forward.
