Two people are in custody in connection with the disappearance of 20-year-old South Carolina woman Heather Elvis, Horry County Police officials confirmed to

Elvis, of Myrtle Beach, S.C., was last heard from in the early morning hours of Dec. 18, after the young woman went on a date. Her 2001 Dodge Intrepid was found abandoned the next day on the Peachtree Boat Landing in Socastee, Horry County.

Several law enforcement agencies, including the U.S. Marshal's Office, descended early Friday on a Myrtle Beach residence, where a search warrant was served.

"The search warrant was executed in an attempt to identify potential evidence based on new information obtained through expert analysis of previously seized surveillance tapes in the area along with financial discrepancies filed with the State of South Carolina on behalf of the occupants of the residence," the Horry County Police Department said in a statement. 

The names of the two individuals taken into custody were not released. 

Address records show that 37-year-old Sidney Moorer lives at the residence being searched, though it is not known whether he was taken into custody. Cell phone records show Elvis communicated with Moorer as late as 6 a.m. on Dec. 18. Police records also state that Elvis had a relationship history with Moorer.

Investigators said Elvis was driven home by her date to the apartment she shared with another woman in River Oaks some time before 2 a.m. on Dec. 18. The young man with whom Elvis met for the date has been ruled out as a suspect, a source close to the investigation told Authorities believe that at some point later, Elvis drove herself to the boat landing, though the reason remains unknown.

A task force of about 15 investigators has been assigned to the case, including two Myrtle Beach police detectives and individual investigators from the U.S. Marshal's Office and FBI.

Authorities as well as more than 300 volunteers have scoured heavily wooded areas surrounding the boat landing for any sign of Elvis since her Dec. 18 disappearance.

Anyone with information on the case is urged to call the Horry County Police Department at 843-915-5350.
