A Buffalo man has pleaded guilty to multiple drug charges after selling heroin and fentanyl to two people who later died from overdoses.
Aaron McDuffie, 23, will face at least 20 years in prison.
In June 2015 a Cheektowaga man died after using the drugs McDuffie sold him.
The Cheektowaga victim's phone helped identify McDuffie as the person who sold him drugs the night he died. Investigators also say McDuffie told another customer he gave the man a potent batch and warned him not to use as much.
A West Seneca man died under the same circumstances in November of 2016.
Under federal law, McDuffie is responsible for the deaths the two men.
The charges carry a maximum life sentence.
McDuffie will be sentenced in May.
