San Diego Police Chief Scott Wahl says the mother of one of the suspected shooters contacted law enforcement shortly before the attack at the Islamic Center of San Diego. CBS News reports she alerted police that her son was missing and that he had multiple weapons, along with information about her vehicle. The Los Angeles Times describes a period of confusion in the lead-up to the shooting, saying one of the mothers reached out about two hours beforehand, warning that her son was suicidal and had taken firearms from his father’s safe. That outlet also reports police took nearly 90 minutes to respond to the initial call, during which time they worked to assess the threat. The Daily Mail similarly characterizes the mother’s efforts as urgent and aimed at alerting authorities before her son and his friend opened fire. Across the accounts, the central points focus on prior contact with police, the information provided about weapons and suicidal behavior, and delays in police response as the attack occurs later that day.
