PATCHOGUE, N.Y. - Brian Laundrie had the personality of a "chameleon" who sometimes lost his temper and always had clean hands despite working with plants and soil, according to a former co-worker from his native New York."He never came across as the kind of person that would be the killing type," Michael Livingston, who said he worked with Laundrie, 23, in parts of 2017 and 2018, told Fox News Digital. "But he did have that tendency to be — I don’t wanna say the wrong thing and make him sound worse than he already is — he was kind of a guy who would get p---ed off pretty quick."Livingston, 31, was a landscaper for a Long Island garden center, where Laundrie worked the sales counter and did other odd jobs, he said.GABBY PETITO'S MOTHER SAYS.
