Questions raised over 'bothersome’ detail in Brian Laundrie autopsy

A former FBI agent has cast doubt over Brian Laundrie's final moments after highlighting an obscure detail in his autopsy.

Laundrie's remains were found in a nature reserve near his Florida home weeks after vanishing on September 13.

In a note left behind, the 23-year-old admitted to killing his girlfriend Gabby Petito, the FBI said. An autopsy had earlier ruled Ms Petito, 22, died from strangulation.

Her body was found on September 19 after the pair travelled across the US in a van, before Laundrie returned home alone following a disagreement with his partner.

Jennifer Coffindaffer, whose FBI career spanned 25 years, told NBC affiliate WFLA the autopsy details of Laundrie's handling of the weapon used to end his own life are "bothersome".

The autopsy concludes Laundrie inflicted a fatal injury with his left-hand however states he was "right hand dominant".

"It does not fit with a right-handed person committing suicide with their off-hand," she said.

While stressing she was not a "conspiracy theorist", she said it was a detail that could not be ignored.

“To me, the case doesn’t end because it ends with a question mark," Ms Coffindaffer said.

That question raises the possibility Laundrie was assisted in his suicide.

Laundrie's skeletal remains were identified on October 22 using dental records after his remains had been submerged in a marsh for weeks.

Laundrie was the only person of interest over Ms Petito's death, with the FBI stating in January he was solely responsible for her homicide.

Ms Petito's disappearance and the subsequent discovery of her body not only gripped the US but made headlines across the globe.
