The U.S. Marshals added Casian-Garcia and Medina to the 15 Most Wanted list in February, saying they have been charged with aggravated murder, four counts of rape of a child, and three counts of assault on a child.
In May 2021, Pasco Police began investigating the disappearance of Casian-Garcia’s son, Edgar Casian, though he had not been "credibly accounted for" since September 2020. On Feb. 5, 2022, hikers in Benton County, Washington, found human remains, and several law enforcement agencies began investigating. The remains were later identified as Edgar’s, and in April 2022, a nationwide warrant for first-degree went out for Casian-Garcia and Medina’s arrests.
He had been tortured to death. Pasco Police Detective Jon Davis said Edgar’s death was "the worst case I’ve come across in nine years as a detective."
Several weeks after Pasco Police started looking into Edgar’s disappearance, two of Edgar’s siblings, ages 3 and 8, were found in Tijuana "under alarmingly dangerous conditions." The NCMEC reports the two young girls "showed signs of severe physical and sexual abuse."
The older child told police she and her sister had "been subjected to unimaginable torture and that she’d been raped while living in Washington."
The U.S. Marshals allege Casian-Garcia was most likely sex trafficking the children, including Edgar.
According to the U.S. Marshals, their five children who were also missing and endangered were rescued and taken into protective custody of the Washington State Department of Children, Youth and Families.
The U.S. Marshals said those on the 15 Most Wanted list "tend to be career criminals with histories of violence who pose a significant threat to public safety," and are "considered the 'worst of the worst.'"
Casian-Garcia and Medina remain in Mexico pending extradition.
