Raquel Pitsenberger, 55, was found mortally wounded inside a home in the 1300 block of Fern Avenue in Imperial Beach, California, on December 4, 2021. Deputies also discovered her son, 36-year-old Marco Tony Valadez Jr., critically injured; he was later pronounced dead at a hospital. The deaths were investigated as a double homicide that deeply affected the local community.

Authorities identified 47-year-old Marco Antonio Valadez Jr. as the primary suspect and alleged the killings were intended to silence family members who were potential witnesses to a sexual assault reported to have occurred days earlier involving an 18-year-old family member. Valadez was arrested in Mexico and extradited to the United States on December 16, 2021, and faced charges that included two counts of first-degree murder, felony sexual assault, and failure to register as a sex offender, with special circumstance allegations for multiple murders and killing a witness.

Are there witnesses, neighbors, or anyone with information about the events around Fern Avenue on or shortly before December 4, 2021, who could help investigators?
