"Drug boss Martin Shkreli, 32, also allegedly gained access to social media accounts belonging to that ex-employee, and contacted him and his relatives directly, including his teenage son and wife, as he accused the worker of defrauding Shkreli's then-pharma company, Retrophin.

"Your husband had stolen $1.6 million from me and I will get it back. I will go to any length necessary to get it back," Shkreli allegedly wrote the wife of former Retrophin employee Timothy Pierotti in a January 2013 letter, according to court documents.

"Your pathetic excuse of a husband needs to get a real job that does not depend on fraud to succeed ... I hope to see you and your four children homeless and will do whatever I can to assure this," Shkreli allegedly wrote."
