JACKSON, Wyo. — The search for 22-year-old Gabrielle Petito continued Saturday, and now includes her boyfriend, Brian Laundrie, in an investigation that spans the country.

In Wyoming, officials are looking specifically in the Spread Creek Dispersed Camping Area, which is located in the Bridger-Teton National Forest on the east boundary of the Grand Teton National Park.

The area was closed to the public while crews conducted the ground surveys.

They asked anyone that saw Petito, Laundrie, or their vehicle in that area between Aug. 27 and 30 to contact the FBI.

Police started looking for Laundrie Saturday in a wildlife reserve in the Sarasota, Florida area called the Carlton Reserve.

The efforts come less than 24 hours after police met with Laundrie’s parents at their home, per their request, and were told they last saw him on Tuesday.

Officials called off search efforts just before 6 p.m. Saturday, adding that they will start back up in the morning. 

They also said nothing had been found during their search.

Reports went around that afternoon that authorities found a body during their time in the reserve, but North Port police confirmed that information is “completely fake.”

Officials said Laundrie is a person of interest in the case and hasn’t been cooperative in the investigation.

“We’re still focused on what we need to do and that’s to find her, and we’re determined to do that,” said Jim Schmidt, step-father of Gabby Petito.

Petito’s family is not giving up hope, and they’re frustrated with reports that describe Laundrie as “missing.”

They shared a statement with KSL through their family spokesperson in Wyoming, saying, “We do not consider Brian missing – Gabby is missing, he was home!! He left – he is hiding and running from the authorities.”
