Gabby Petito died by strangulation -coroner

Weeks after the body of 22-year old Gabby Petito was found near a Wyoming campground, one question is answered.

"In the manner of death of Gabrielle Venora Petito, we find the cause and manner to be: cause, death by strangulation, and manner is homicide."

Teton County Coroner Dr. Brent Blue said Petitio was killed three to four weeks before searchers discovered her body on September 19th.

The young woman had vanished on a road trip with her boyfriend, 23-year old Brian Laundrie, who has been missing for nearly a month.

Petito was last seen alive on Aug. 26.

Traveling west across the U.S., Petito documented their "van life" on social media with videos and pictures depicting a loving couple on an adventure.

Laundrie returned home to Florida without her on Sept. 1, driving Petito's white van.

After Florida police named Laundrie a person of interest in the case, police in Moab, Utah, released bodycam footage from a traffic stop after a caller reported seeing Laundrie striking Petito. No charges were filed.

Laundrie refused to talk to police and has not been seen since Sept. 14.

A federal grand jury indicted Laundrie on a charge of fraudulently using Petito's bank debit card between Aug. 30 and Sept. 1.

He has not been charged in her death.
