started yet. we re not sure if we re going to get information released today. we want to show you new video that we have in as their family waits for answers. we re getting our first aerial views of the scene where investigators found the human remains believed to be of those of the missing 22-year-old. we just got this family statement in saying this. i want to personally thank the press and news media for giving the petito and schmidt family time to grieve. we ll make a statement when gabby is home. ly contact you to a range a time and location. here in wyoming, the criminal investigation of what happened in the days leading up to petito s disappearance presses on. we ve been listening to the 911 call that was released yesterday from utah that led to the traffic stop of petito s van with her boyfriend, brian laundrie and driving and being pulled over. the person that called 911 near the coffee shop said he saw a
they soon discover that a misidentification could be possible. there were peaks there that, sure enough, looked like they might have been interpretable as ethylene glycol. what looked like antifreeze may have actually been something else. shoemaker and sly contact prosecutor george mcelroy about obtaining the methods the lab used when they got the original results. mcelroy agrees and gives the scientists full access to the data. the one outside laboratory was using a method called gas chromatography. it s a method where you inject compounds into this column and they separate based on their boiling point. each compound has a characteristic boiling point. the doctors test ryan s sample using the same equipment as the lab that got the initial results. a compound found in ryan s blood does have a peak in the position

been present in ryan s blood and that the lab technician may have made a mistake. under dr. sly s supervision, shoemaker runs tests on ryan stallings blood sample to see if they can detect elements that can be mistakenly read as ethylene glycol. the scientists begin by looking at boiling points for various compounds. each compound boils at a certain temperature and is represented by a peak on a graph. they soon discover that a misidentification could be possible. there were peaks there that, sure enough, looked like they might have been interpretable as ethylene glycol. what looked like antifreeze may have actually been something else. shoemaker and sly contact prosecutor george mcelroy about obtaining the methods the lab used when they got the original results. mcelroy agrees and gives the scientists full access to the data. the one outside laboratory was using a method called gas
