Emma Frances Tresp, 71, of North Little Rock, Arkansas, disappeared on August 31, 1998 while driving from her daughter’s home in Stillwater, Oklahoma to a religious retreat at the Benedictine Monastery of Our Lady of Guadalupe near Pecos, New Mexico. She was last seen about 3:00 PM stopping for gas in Santa Rosa, New Mexico. Emma was described as mentally sharp but prone to getting lost while driving.

On September 13, 1998 her white 1997 Honda Civic was found locked and stuck on a large rock on Forest Road 375, 10–15 miles from State Route 63 in a heavily wooded part of the Santa Fe National Forest. The oil pan was damaged, most of her belongings remained in the car, and her purse was missing. Authorities believe she may have left the vehicle to seek help, but searches turned up no trace of her.

Her family reported her missing on September 8 after she failed to arrive at the monastery. The case remains an endangered missing person investigation with no substantial clues publicized. If anyone saw Emma or her car along that route in late August 1998, please share what was noticed.
