PHOENIX — Phoenix police have arrested two teenagers in last year's shooting deaths of two coffee house workers.

Sgt. Tommy Thompson said Wednesday that two boys, 15-year-old Castulo Cervantes and 16-year-old Antonio Palafox-Zermeno, have been booked into Maricopa County jail on several counts, including first-degree murder.

Authorities say 41-year-old David Bessent and 24-year-old Zachary Walter were shot during an armed robbery Oct. 5 while walking from Jobot Coffee in the Roosevelt Row neighborhood.

Walter was fatally wounded. Bessent succumbed to his injuries five days later.

Investigators say the suspects fled the scene in a white Dodge Durango.

Thompson did not say what evidence led investigators to arrest the teens.

Cervantes and Palafox-Zermeno have been charged as adults in the shootings.

Police believe at least two others are involved.
