BIG BEND NATIONAL PARK, Texas (Nexstar/KXAN) — A man and daughter last seen in Big Bend National Park were found across the border in Mexico, park officials said Tuesday.

A truck found abandoned in the park prompted a search for the missing 49-year-old Texas man and his 9-year-old daughter last seen Jan. 28.

According to a release, the two traveled from Fort Stockton to Big Bend National Park in a blue 2005 Dodge 1500 truck on Jan. 28. The truck was later found at the northern end of the remote Old Ore Road with many of their personal belongings inside.

Residents in Boquillas, a Mexican community on the other side of the Rio Grande, notified the National Park Service that two people matching their descriptions were in the area and trying to buy food. On Monday, Mexican State Police visited the town and confirmed they were the missing people. Officials said they are healthy.

“An investigation into this incident is still underway. No additional information is available at this time,” NPS said in a release.

The original release said the father and daughter may have been traveling on foot and may not have the proper clothing or equipment to camp inside the park.

NPS thanked all who helped spread the word and investigate, including the NPS Investigative Services Branch, U.S. Border Patrol, U.S. Customs and Border Protection, FBI, Fort Stockton Police Department, the Texas Department of Public Safety and Mexican State Police for their help. Teams hiked the area, drove the backcountry roads, and searched from the air using helicopters.
