Michelle Marie Semenjuk, 63, was fatally shot inside her apartment in a west Phoenix senior living community near 43rd Avenue and Thomas Road on October 26, 2025. Neighbors recalled her as a kind person who repaired electric bikes and scooters. Phoenix police arrived about 4:41 p.m. after reports of a shooting and found Semenjuk with at least one gunshot wound; she was taken to a hospital in extremely critical condition and later died.

Investigation led to 58-year-old Salvador Najera Jr. A witness said a man, later identified as Najera, was seen walking away from Semenjuk’s apartment right after gunfire. Najera reportedly called family members and admitted to shooting someone before leaving in his vehicle. Officers located and arrested him; during an interview he confessed to the shooting and said he was a prohibited possessor. He was booked on murder and misconduct involving weapons charges. The motive and any relationship between Najera and Semenjuk are still under investigation.

If anyone knew Michelle, lived in that community, or saw activity near 43rd Avenue and Thomas Road that afternoon, please share what might help clarify what happened.
