The disappearance of Sudiksha Konanki, a 20-year-old University of Pittsburgh student, has taken a troubling turn as Venmo transactions highlight her final movements before vanishing from a resort in Punta Cana, Dominican Republic.

The first payment was made at 2.54 pm on March 5 to an unnamed new user. Konanki used a sailboat emoji to describe it. The second was made at 3.38 pm

Konanki's week-long disappearance has left investigators puzzled and led her parents to call for an expanded search effort for their daughter, a pre-med student.

Sudiksha Konanki, an Indian citizen and permanent resident of the United States, was last seen on March 6 at the Riu Republic Resort in Punta Cana.
