The Mesa Police Department has booked a 20-year-old suspect into jail after four separate shootings in Mesa and one in Phoenix left four people dead, and one person injured on Friday and early Saturday morning.

Iren Byers, 20, has been booked into jail on four counts of first-degree murder and one count of attempted first-degree murder.

On Friday afternoon around 3:40 p.m., Phoenix police say Byers shot a man next to a canal near 24th and Oak Streets in Phoenix. Officers identified the man as 41-year-old Nicholas Arnstad and pronounced him dead at the scene.

Later that evening, just before 10:30 p.m., officers were dispatched to Beverly Park near Alma School Road and Main Street for a report of a person found dead. Officers discovered the body of a 41-year-old man.

While still at the park, officers heard shots fired nearby and other officers began to search the area, police said. At about 12:15 a.m. on Saturday, officers found a 36-year-old woman with injuries at Stewart and Main Street. The woman was transported to the hospital. As of Sunday morning, police said the woman is in stable condition.

Another person called police just before 1 a.m. on Saturday to report a dead man near a bus stop at Country Club Drive and Second Avenue. Officers arrived and found the body of another 41-year-old man.

Officers saturated the area in search of the suspect and other victims and ultimately discovered another body just after 2 a.m. near South Extension Road and Main Street. This person has not been identified but is believed to be a man, police said.

Mesa police were able to preliminarily link at least one spent shell casing from most of the shooting scenes to the same handgun, a 9mm. They also found a match to a shell casing that was used in a Phoenix homicide on Friday afternoon, just before 2:45 p.m.

Phoenix police also learned that the suspect involved in the Mesa homicides matched the description of the suspect involved in the Phoenix canal shooting.

During the investigation, officers reviewed video footage from various sources in the area of the shootings. This included footage from the light rail, Circle K and a residential home equipped with a Ring camera. They found the same man in all the videos, wearing the same clothing as reported by witnesses at the time of the shootings.

Byers was located near North Extension Road and Main Street in Mesa and was taken into custody for a misdemeanor charge of trespassing. He was cooperative with officers from Mesa and Phoenix Police Departments and took responsibility for all five shootings during questioning, police said.

Byers told officers where they could find the clothing he wore and the handgun he used during his crime spree, which officers recovered at Byers' residence, after completion of a search warrant, police said.

Det. Brandi George, a spokesperson with Mesa Police Department, said victims' names will be released once next of kin is notified.
