Amanda Johnson was 30 when she was shot in the head during a confrontation inside a small Peoria home near 67th Avenue and Greenway Road on October 25, 2014. She had been staying about a week with Rose Perry while separated from her husband and their two children. According to investigators’ accounts, an argument in the living room involved Johnson, 53-year-old Mark Anthony Barquera, and another woman who had been staying there. Barquera produced a handgun, pointed it at Johnson’s head and fired a single close-range shot. Perry covered Johnson with a blanket until officers and paramedics arrived; Johnson was taken to a hospital and pronounced dead.

Police found Barquera at the residence and arrested him; officers reported he spoke about demonic forces and the living room as a portal, and a small bag later tested positive for methamphetamine. He was booked on suspicion of second-degree murder and drug possession; court records show he was later convicted of manslaughter and admitted to the Arizona Department of Corrections in 2016. No other suspects have been publicly identified. If anyone knew Amanda, her movements that week, or witnessed the confrontation, please share what was seen or heard.
