U.S. Immigration and Customs Enforcement (ICE) detained a man in Maryland as local investigators searched for his girlfriend, who was last seen March 31.

The Charles County Sheriff’s Office said it is investigating the disappearance of Lesbia Mileth Ramirez Guerra, 23, of Waldorf, Maryland.

While Guerra was last seen on the night of March 31 at her home on Adams Court, her boyfriend, who the sheriff’s office has not named, reported her missing on April 2.

Along with living with several other individuals at the residence, Guerra also reportedly lived with her boyfriend, who is the father of her two children.

Investigators also learned that a red Toyota 4Runner owned by the family was at the residence on the day Guerra went missing, leading detectives to suspect it was involved in her disappearance.

Anyone with information about Guerra’s whereabouts or who may have seen the Toyota 4Runner between March 31 and April 2 is encouraged to contact Detective Burgess at 301-609-6494.
