An affidavit filed by a Homeland Security Investigations in connection with a search warrant alleges that Howard developed the “Banana Plug” application, which was available on the Apple App Store.

The app offered for sale contraband, including cocaine, “Molly,” and “Shrooms.” It also invited customers to make special requests. Posters advertising the application had been hung up around the UC Santa Cruz campus.

Upon discovering the posters and the application, a UC Santa Cruz police officer, in coordination with HSI, used it to request a purchase of marijuana and cocaine and then communicated with Howard via Snapchat to set up the purchase.

An undercover HSI agent made that purchase and separately continued to communicate with Howard on Snapchat to set up three additional purchases of controlled substances.

The third and fourth purchases were for more than five grams of methamphetamine. At the fourth meeting, UC Santa Cruz police officers arrested Howard before any payment was made.
