Costa Mesa, CA
Allison Castillo, a 15-year-old soccer player from Costa Mesa, was fatally stabbed in a seemingly random attack on August 9 while visiting a friend in her former neighborhood on Shalimar Drive. The tragic incident occurred at approximately 12:30 p.m. when she was attacked by 31-year-old Matthew Juarez, who has a criminal history and known gang affiliations. Authorities classify the attack as gang-related, although Castillo had no connections to gangs and did not know her assailant.
Despite immediate medical attention that temporarily revived her, Castillo succumbed to her injuries hours later at the Orange County Global Medical Center. Juarez was arrested later that day in Anaheim.
Castillo was not only a dedicated student at Newport Harbor High School but also an aspiring professional soccer player, having played the sport since she was 3 years old. Recently, she received a full-ride scholarship to attend a soccer camp in Spain through the LaLiga Academy. She had been enrolled in a county education program to recover school credits missed due to her commitments in soccer competitions.
Family and Community Mourning
The unexpected loss has left Castillo’s family devastated. Her mother, Yohana Legaspi, was en route home from a doctor’s appointment when she received the call about her daughter’s tragic event. Legaspi is currently recovering from a stem cell transplant for cancer and is out of work, complicating the family’s financial situation regarding funeral and burial expenses.
In the wake of this tragedy, the family is organizing fundraising events to cover funeral costs, including food sales and a community carwash event. To further assist, they have set up a GoFundMe campaign titled ‘Loving Tribute to Allison’s Beautiful Soul.’ This initiative aims to ease the financial burden on the family during this difficult time.
Community’s Response
The Incident’s Context
Matthew Juarez’s background includes three felony convictions, underscoring a long history of criminal behavior, which raises concerns about community safety surrounding the incident. As police continue their investigation, many in the Costa Mesa area are left grappling with the implications of such violence occurring in their neighborhood.
As the investigation continues, the community’s focus is on supporting the Castillo family during this harrowing time. The emphasis remains on remembering Allison not just for her tragic end but for the lively spirit and passion she brought into the world of soccer and her loved ones’ lives.
