Two males who police say are responsible for the death of 21-year-old Arizona State University student Zachary Marco each were charged with first-degree murder and armed robbery, the Maricopa County Attorney’s Office announced on Wednesday.
Louis Eugene Harper, 20, who Tempe police arrested two weeks ago, and Marion Anthony Patterson, 17, who was arrested on Monday, were charged through a direct complaint on Wednesday filed by the Maricopa County Attorney’s Office.
Both suspects are Tempe residents. The Associated Press reported that bond was set at $1 million apiece.
Marco, an honors student at ASU, was shot about 9:30 p.m. on Oct. 17 in the 1100 block of East University Drive while walking home from the school library, according to police. He died at the scene, police said.
After police arrested Harper, officers executed search warrants and confiscated cell phones containing text messages between Harper and Patterson discussing robberies and planning to rob someone. Police later recovered Marco’s computer bag, which had the fingerprints of the two suspects on it, according to police.
Tempe police also confirmed on Wednesday there was a third person arrested in connection with Marco’s death, but did not release that person’s name, citing concerns for his safety.
