A 32-year-old Arizona man named Martine Mayorquin has been charged with first-degree murder and child abuse after allegedly strangling his 28-year-old girlfriend Katlynne Roy to death in front of their three young children, ages 7, 5, and 3. Mayorquin reportedly admitted to police that he put Roy in a 'rear naked choke hold' for three minutes, took a two-minute break, and then strangled her again for another five minutes until she was 'no longer responsive'.

Why it matters

This tragic incident highlights the devastating impact of domestic violence, especially when it occurs in front of children. It raises questions about the need for better mental health resources, domestic abuse intervention programs, and stronger legal protections for victims and their families.

The details

According to the police affidavit, neighbors called the property manager after hearing screaming and crying children in Mayorquin and Roy's apartment. The property manager found Roy unresponsive on the floor with Mayorquin standing over her, while the children were huddled in a bathroom crying. Police arrived and pronounced Roy dead at the scene. Mayorquin admitted to the 'rear naked choke hold' and said Roy had scratched his chest and back while fighting back.

  • On April 15, 2026, police responded to a 911 call about a 'commotion' at the apartment around 6 p.m.
  • Mayorquin's next court date is set for April 24, 2026.
