Major police and FBI activity at Brian Laundrie's parents North Port home, which is now considered a crime scene. Police have been trying to get information from the Laundrie family since September 11, when Petito was officially reported missing by her family.

The FBI could have acted last week when Laundrie was at home but delayed the action. 

Law enforcement now has tracking access for both Brian Laundrie and Gabby Petito’s cell phones. This means they can track where the phones currently are located as well as where they have been. Police do not physically have either of the phones.

Laundrie has been missing for days since he returned home from a cross-country road trip without his fiancée, Gabby Petito. Authorities on Sunday confirmed a body found in the section of Wyoming's Bridger-Teton National Forest.

The FBI confirmed the body of Gabrielle "Gabby" Petito was found on Sunday by law enforcement agents but the cause of death has not yet been determined, with an autopsy set for Tuesday.

Investigators are carrying out a search warrant at the home of Brian Laundrie as work continues to figure out where he may be located.
