Irving Alvarez, 23, has been identified as the second suspect arrested in connection with Tuesday's fatal shooting in downtown Yakima. Alvarez was taken into custody at a Selah home. He is facing a charge of first degree murder and police say he is a known gang member in the Yakima area. Meanwhile, the other suspect who police say was the shooter. Daniel Perez, Jr., 15, is set for a hearing in county juvenile court later today to determine if he will be charged with murder in adult court. He is being held on a half million dollars bail. Alvarez made his first appearance in court on Thursday. Authorities say the two suspects are responsible for the death of rival gang member, 26-year-old Octavio Rangel.
