Just short of her ten-year anniversary with the Upland Police Department and her role as a law enforcement professional, Detective Caitlin Teague has died.
Born in Missouri, she obtained her Bachelor of Arts degree and worked as a social worker, earning a master’s degree in public administration.

In 2014, she changed professions, becoming an officer with the Upland Police Department.
Teague worked patrol for several years, earning the position of field training officer.
In May of 2021, she was designated a school resource officer, in which capacity, according to Upland Police Chief Marcello Blanco, “She touched thousands of lives, bridged the gap between law enforcement and our youth, and became a role model to countless students who looked up to her.”
In July of 2022, Teague was promoted to the rank of detective. She worked property crimes and crimes against children/elders. In addition, she was the team leader of the Upland Police Department Crisis Negotiation Team. In addition, she was for four years the department’s Explorer Program advisor for several years, and also functioned as the department’s taser and CPR instructor. Most recently, in the face of rising fentanyl overdose deaths, she was tapped by Chief Blanco to instruct her colleagues in the use of Narcan.
A Rancho Cucamonga resident, she suffered, on November 24, an unanticipated medical emergency, requiring hospitalization. She succumbed that evening, 27 days shy of what would have been her 41st birthday.
Detective Teague is survived by her husband, UPD Lieutenant Lon Teague, her mother, father, three sisters, one brother, two brothers-in-law, two nephews, one niece, and three stepchildren.
