Agents across the country are rallying to support a California agent who lost both of her sons in a Christmas night car crash.

Twin 16-year-olds Mark Anthony and Michael Angelo Urista were two of the three teens killed when the Hyundai sedan they were in veered into a northbound lane and hit a utility pole. Their mother, Ana Lilia Reynoso, is a Realtor running her own bilingual brokerage in San Mateo County called Ana Reynoso-Realtor, or Casas de Ventas en el Tri-Valle in Spanish.

The cause of the crash on Foothill Road in California’s Pleasanton has not been determined. Families who lived in the surrounding area reported hearing a loud bang as they were sitting down to open their Christmas presents.

Another teen, Javier Ramirez, was also killed in the crash while two of the other teens in the car have been hospitalized with serious injuries. One of the boys hospitalized is also Reynoso’s nephew, according to a family friend’s Facebook page.
