“We urge individuals with knowledge of Mr. Laundrie’s role in this matter or his current whereabouts to contact the FBI,” the tweet read in part.
Laundrie, 23, and Petito, 22, embarked on a road trip through the American west in July. The couple had posted online regularly about their travels with the hashtag #VanLife, but those posts abruptly stopped in late August.
Petito was reported missing on Sept. 11 after Laundrie returned home to Florida without her. Petito’s body was found in a national park in Wyoming on Sunday.
Three days after Petito was reported missing, Laundrie himself disappeared, according to his family. They say they haven’t seen him since Sept. 14.
“While this warrant allows law enforcement to arrest Mr. Laundrie, the FBI and our partners across the country continue to investigate the facts and circumstances of Ms. Petito’s homicide,” the FBI said.
