Vilma Susana Lux Lopez was 17 when she and her 15-year-old sister Amelia Adelaida Lux Lopez left their foster home in Ravenna, Michigan. They were last seen on December 13, 2020, after having been placed in foster care following detention by Border Patrol in Texas when they entered the United States without documentation. Both sisters are of Guatemalan descent and had limited English.

Authorities say the girls left the foster parents’ home sometime during the night and were initially classified as runaways. Investigators’ prevailing theory is that they fled to reunite with family members, but details about what they were wearing or whether they took any belongings have not been released. The Muskegon County Sheriff’s Office is handling the investigation, and the sisters’ records are listed in the National Missing and Unidentified Persons System.

If anyone knew Vilma or Amelia, saw them after December 13, 2020, or has information about family they might have tried to reach, please contact the Muskegon County Sheriff’s Office.
