The suspect, identified as Martine Mayorquin, is also charged with three counts of child abuse in connection with the tragic death of 28-year-old Katlynne Roy, as reported by the Tucson Police Department. Authorities were alerted shortly before 6 p.m. on Monday, responding to a disturbance at a residence located in the 600 block of North Dodge Boulevard. Neighbors had contacted 911 after hearing what was described as a “commotion” coming from a nearby home.

According to a probable cause affidavit acquired by Law&Crime, concerned neighbors reached out to the property manager upon hearing screams and the cries of children from a nearby apartment. Upon entering, the property manager discovered the victim on the ground, with Mayorquin standing over her. Meanwhile, the children were found in a bathroom, visibly distressed and crying.

Police officers who arrived at the scene found the woman unresponsive on the floor, exhibiting signs of apparent strangulation. Tragically, she was pronounced dead at the location.

Officers arrived at the apartment and found an unresponsive woman on the floor with “apparent strangulation trauma.”

She was pronounced dead at the scene.

Cops arrested Mayorquin after he “admitted to strangling the victim twice in front of their 7-year-old, 5-year-old and 3-year-old until she was no longer responsive,” prosecutors said at a first appearance hearing posted by local CBS affiliate KOLD. After receiving his Miranda rights, Mayorquin allegedly said he put Roy in a “rear naked choke hold” for three minutes. He took a two-minute break and then proceeded to place Roy into the hold again for another five minutes, the affidavit stated.

Mayorquin had scratches on his chest and back which he said was from the victim fighting back, per cops.

At his first appearance, his public defender argued for a lower bond, stating his client has no previous criminal history. But a judge granted the prosecution’s request for a $1 million bond.

The defendant remains in the Pima County Jail. His next court date is set for April 24.
