Paulino Norberto Del Mundo, also known as Pauline, Paula, or Paulino Norberto Del Mundo Jr., was 59 when last seen during a layover at Dallas–Fort Worth International Airport on September 14, 2019. A naturalized Filipino‑American and certified nursing assistant from Tampa, she identified and lived as a transgender woman and was described by family as bubbly and close‑knit. She called her sister just before 6 p.m. Dallas time saying she had changed her mind about continuing to Cozumel and needed help booking a return to Tampa; family members later described her tone as on the verge of desperation.

Del Mundo is described as about 5 feet 6 inches, medium build, 130–140 pounds, long brown hair, brown eyes, double‑pierced ears, a flower tattoo on her right forearm and a light‑brown birthmark on her side; she used full dentures and had recent rotator cuff surgery and limited mobility. The area where she disappeared includes construction, ravines, swampy brush and a small lake, and searches in and around that zone found no trace. If anyone saw Paulino Del Mundo at DFW on September 14, 2019, or has information about her movements after she left Terminal C, please contact DFW Airport Police, the CUE Center for Missing Persons, or the Philippine Consulate contacts provided by the family.
