Authorities in South Carolina are continuing to search for a National Guard sergeant who went missing while tubing at a lake over Memorial Day weekend.

The victim has been identified as National Guard Staff Sgt. Porsha Griffin, NBC affiliate WYFF, Fox affiliate WHNS and CW affiliate WIS reported.

Griffin was tubing behind a boat on Lake Greenwood without a life jacket on Saturday, May 25, and didn't resurface, the South Carolina Department of Natural Resources (SCDNR) posted on X (formerly known as Twitter). They added that authorities responded the same day and that divers were dispatched.

According to WHNS, Griffin went tubing with three other people, with authorities confirming to the outlet that the others were safe.

The SCDNR and the South Carolina National Guard did not immediately respond to PEOPLE's requests for comments.

Porsha, who is also the mom of a 9-year-old girl, had just received her degree in nursing in December, according to the outlet.

Her mom added, "She was that supportive person [that you] could call on for anything."
