An Arizona man’s two-week shooting spree left two individuals dead and a home riddled with bullets, all while he roamed the area on an e-bike, according to police and the victims’ families.

Adalberto Pablo Cordova Torres, 21, faces two first-degree murder charges for the deaths of Marcus Adams, 45, and Andreas Olguin, 29, as reported by the Phoenix Police Department. Additionally, he is accused of discharging a firearm at a residential property.

The violent spree allegedly commenced on November 11, when a homeowner near 16200 North 1st Drive discovered multiple bullet holes in their dwelling. Adams was reportedly shot on November 24 near 19th Avenue and Greenway Road, and Olguin was killed less than a week later, on November 29, at a bus stop close to 19th Avenue and Thunderbird Road. Both victims were declared dead at the scenes of their respective shootings.

“I never imagined my son would be targeted while simply sitting at a bus stop,” shared Olguin’s mother, Toni Perez, in an interview with local Fox affiliate KSAZ. “It’s shocking that someone would attack him without any reason.”

Perez revealed to KSAZ that detectives informed her the suspect did not know her son, suggesting the attacks were random. “This is where my outrage stems from,” she expressed. “No one deserves such fate. I will seek justice for my son and for Marcus. They both deserve it.”

Police say Adams was found around 3:15 a.m. on Nov. 24 after being shot nine times. Investigators recovered 14 spent shell casings near the scene. Olguin was shot 11 times and 15 spent shell casings were found near the bus stop; the shooting happened at around 2 a.m., according to cops.

“Once the ballistic evidence from the three cases was fully processed, a correlation between the cases was found and all three cases were linked through this ballistic evidence,” the Phoenix Police Department says in a press release. “Case agents of all three cases began to work together in an attempt to identify the suspect.”

Investigators discovered additional evidence, including surveillance footage, linking Cordova Torres to each of the crime scenes, which led to his arrest on Thursday.

Court documents obtained by local TV station KTVK outline how Cordova Torres was allegedly caught on video approaching both Adams and Olguin before opening fire on them and fleeing on an e-bike. He is accused of using a 9mm handgun in all three shootings.

Police say Cordova Torres works at a business that is between 2 and 8 miles from each of the shooting sites. His employer allegedly confirmed that he had been working nights before the murders occurred.

Cordova Torres is being held on a $3 million bond and is due in court on Dec. 11.
