Last week, the Riverside County Sheriff's Department found 36-year-old Esmeralda Casillas, of El Cajon, and her mother 68-year-old Ofelia Casillas shot in a car in Moreno Valley. Both women were later pronounced dead at the hospital.
FOX 11 was told the shooting stemmed from a child custody exchange last Friday. Both Esmeralda and Ofelia Casillas were getting ready to drop off Esmeralda's two twin sons to the younger Casillas' ex-boyfriend, as the custody exchange is scheduled to take place every Friday.
Following the shooting, authorities arrested Salvador Velasquez, the father of the twin boys and Esmeralda Casillas' ex-boyfriend, in connection to the double murder.
FOX 11 was told Velasquez's parents are now taking care of the twin boys, a news that leaves Esmeralda Casillas' relatives concerned.
"We have the possibility that something bad happened to these kids," said Adriana Toledo, a relative of Esmeralda Casillas.
The family says they are talking with Child Protective Services on how the twin boys' custody situation will be handled moving forward.
