Gabby Petito sleuths think she was sad as they spot hidden meaning in Instagram pic posted after she shared knife emoji

that appeared to show her outdoors wearing a gray top and white pants.

Gabby captioned one post: "I'm blue da ba dee da ba daa 🦋 #imblue."

In the second post, she captioned it: "Blue his house with a blue little window And a blue Corvette And everything is blue for him 🧊✈️🤍🔹🦕. #blue."

Sleuths believe the 22-year-old was sending hidden messages about her mood, as one commented: "Is she trying to say she’s sad??"

Another person chimed in, saying: "Blue as in sad???"

Despite their concerns, Gabby's caption simply referred to the Eiffel 65 song Blue (Da Ba Dee).

'WEIRD IRONY'

Eagle eye spies also highlighted Gabby's June 23, 2020 post, where she shared a picture of Laundrie and herself at Sope Creek Stream in .

What sleuths questioned in the June 2020 post was the book Gabby was reading, Chuck Palahniuk's Fight Club, which follows the experiences of an unnamed protagonist struggling with insomnia.
