Martin John Bloom, 56, was shot and killed following a road‑side confrontation on the west side of Tucson on June 20, 2024. Deputies say the encounter began after a minor rear‑end collision at West Ajo Highway and South Kinney Road; Bloom was reportedly standing beside the other vehicle when a single shot struck him. He was taken to a hospital and pronounced dead.

Witnesses provided a vehicle description and a license plate that led Pima County Sheriff’s deputies to a 77‑year‑old man named Robert Ryan, who was arrested a short time later and booked on second‑degree murder with bond set at $500,000. Authorities say the investigation is ongoing and that no other suspects are believed to be outstanding.

Are there any witnesses or dashcam recordings from that intersection on June 20 who could help clarify what happened during the altercation?
