Riggitano, 22, allegedly was on Aderall and Klonopin when she jumped into the Hudson River at 4:40 p.m. on Jan. 6, which also happened to be her birthday, the Daily Mail reported.
According the several reports, Riggitano had gotten into a Facebook fight with her good friend Alison Tinari, who allegedly wrote her a post that's being considered as a contributing factor in the suicide.
“Go try to kill yourself on Xanax again, you unstable loser. Go f--k yourself and never speak to me again.”
The fashionista left a handwritten note found in her Louis Vuitton bag on the bridge. In the note, she stated that her "friends" were never there and were only interested in gossip. She also singled out four people she wanted excluded from her funeral.
A source has identified the four as Teresa Castaldo, Beth Bassil, Victoria Van Thunen and Samantha Horneff, Fox News reported.
Van Thunen was Riggitano’s business partner at Missfits, a jewelry-design business.
Reports indicate this wasn't the first time Riggitano attempted to commit suicide. Prescription drugs Adderall, used to treat ADHD, and Klonopin, an anti-panic drug, were also found in her bag.
Designer Alex Woo who employed Riggitano part-time said she appeared happy and was liked by everyone.
