Sammy Anthony Terrazas Jr. likely will spend his 18th birthday Friday behind bars.

He was arrested Tuesday at Pueblo Magnet High School, where he is a student, and booked into the Pima County jail on suspicion of first-degree murder in the shooting death of Jesus Duarte, 19. He is being held on a $1 million bond, Deputy Tom Peine, spokesman for the Pima County Sheriff’s Department, said.

Detectives went to the school, at 3500 S. 12th Ave., at about 12:30 p.m. Tuesday as part of their investigation, “but they didn’t expect him to be there,” Peine said.

Terrazas Jr. was in his car in the school parking lot when detectives spotted him. Terrazas first tried to drive away, then got out of his car and ran, Peine said. The homicide suspect did not have a gun on him when he was arrested.

He is suspected of luring Duarte out of his home in the 6400 block of South Camino de la Tierra, north of West Valencia Road just before midnight Sunday and shooting the victim multiple times as he pleaded for his life, Peine said.

During their investigations, detectives learned Duarte was in an intimate relationship with the girlfriend of Terrazas Jr., Peine said.
