What happens if Brian Laundrie isn't found in the coming weeks
CNN
Local and federal investigators have been searching for Brian Laundrie -- the fiancé of 22-year-old Gabby Petito -- for about a month in a Florida nature reserve that spans nearly 25,000 acres.
Petito's parents reported her missing last month following a cross-country road trip the couple began over the summer. Laundrie returned in Petito's van to the couple's North Port, Florida, home on September 1 and went hiking in the nearby Carlton Reserve roughly two weeks later, his parents later told police.
Petito's remains were discovered in Wyoming on September 19. The Teton County coroner determined her cause of death was strangulation. Authorities have not connected Laundrie to Petito's killing, but he is the subject of a federal arrest warrant for events following her death.
