PHOENIX — A Maricopa County man, Luis Alberto Madrigal, was sentenced on Friday to 20 years in prison after pleading guilty to 2nd Degree Murder for killing his girlfriend, 27-year-old Monique-Antwane Gemino, who was also the mother of his child.
According to the Maricopa County Attorney’s Office, on July 7, 2018 Madrigal went to the Monique’s work to get some items from her vehicle. While speaking with her, Madrigal confronted her about his suspicion that she was dating another man. The conversation became heated and Madrigal took a metal object from the back of the car and attacked Monique, causing severe trauma to her body that led to her death.
Madrigal approached a person in the parking lot and asked them to call 911 admitting he had attacked Monique. Madrigal also scratched the word “cheater” into the Monique’s car, later telling police he wanted them to know the reason for the attack.
When officers first arrived at the scene Madrigal refused commands to drop his weapon. He later stated to investigators he was hoping to force the officers to kill him.
