Robin Marie Mendez, 67, of Collinsville, Illinois, was found with severe injuries at her home on Rainbow Drive on November 11, 2021, and was pronounced dead at the scene. An autopsy determined the manner of death to be homicide; she had been fatally stabbed in the face, neck, and shoulder.

Robin worked for more than 30 years as an Assistant Manager at Motor Mart in Collinsville, enjoyed puzzles and reading, and participated in the Bunko Club. She is survived by her husband, Michael Mendez, and other family and friends.

The investigation identified 34-year-old Robert Brittin, who was known to Robin and shared an address in Collinsville, as the suspect. He was arrested and charged with two counts of first-degree murder and with offenses related to motor vehicles after fleeing the scene in Robin’s maroon 2005 Chevrolet Impala; he was held on $2 million bond. Brittin’s prior record included multiple felony thefts, drug possession and other convictions, and he was listed as a registered sex offender and awaiting trial on unrelated charges at the time.
