(AP) — Two Omaha men are improving after being critically wounded earlier this month by a gunman who killed two other people before police killed him.

Police said Tuesday that 31-year-old Aaron Anderson and 46-year-old Angel Cabrera have both improved to serious condition from critical condition. But both men remain hospitalized.

Police say 25-year-old Jorge Abraham Zarazua-Rubio wounded Anderson and Cabrera and killed 25-year-old Anthony Vazzano and 25-year-old Pascual Bautista-Raymundo in the June 15 shooting.

Zarazua-Rubio exchanged gunfire with Officer Coral Walker before Walker killed him.

Police are still investigating the shootings.
