A one-time informant for the Drug Enforcement Administration gave a simple reason for not providing the federal agency incriminating information against a Buffalo drug trafficker who distributed thousands of pounds of marijuana and eventually cocaine and fentanyl pills.

No one asked him for it.

The informant said he could get whatever kind of drug he wanted in 2013 from Ronald Serio, a drug trafficker who lived in a 9,000-square-foot French Provincial mansion on 2.4 acres in Amherst, with a carriage house and tennis court. The informant said he had been inside Serio's mansion about five times and bought marijuana from him.

"I could have gotten to anybody in the Serio organization," the informant testified in retired DEA agent Joseph Bongiovanni's bribery and corruption trial. "They didn't ask me to call him or anything."
