MULTI-INJURY INCIDENT: On Friday, October 29, 1999, at 2:06 PM, five Companies of Los Angeles Firefighters and six LAFD Rescue Ambulances under the direction of Assistant Chief William Ward responded to a multi-victim injury incident at 19010 West Castlebay Lane in the Porter Ranch area. The first company to arrive on scene at the “Castlebay Lane Elementary School” reported multiple children and adults apparently injured by a runaway horse. According to witnesses, the horse was being led by its owner to a Halloween playground assembly. Astride the horse was a costumed teacher. As the horse moved onto the playground , it was startled and bolted. Though neither the teacher nor horse owner needed pre-hospital medical attention, the animal’s abrupt and immense movements caused identifiable injury to four other persons. A ten year-old male student and a nine year-old female student each sustained an abrasion to the right cheek. An eighteen year-old female complained of back pain. A forty-eight year-old woman sustained serious head injury. She, along with the nine year-old girl were transported to Providence Holy Cross Medical Center in Mission Hills. The teenage female and the ten year-old boy were taken to Granada Hills Community Hospital. Several other students were examined by LAFD personnel, but did not require treatment or transportation. The incident was turned over to officials from the Los Angeles Unified School District.
