Stillitano had no visible reaction to the verdict and will be sentenced next month. 

Prosecutors told the jury that on June 16, 2020, 29-year-old Joshua Sutphin died of a drug overdose. They said Stillitano sold him the deadly dose.

Prosecutors said there were cell phone text exchanges between Stillitano and Sutphin about a drug buy the day he died. They also said there were funds transferred by Sutphin to a money app connected to Stillitano. 

Prosecutors explained that Sutphin was struggling with drug addiction but was in a treatment program and had just completed it a day before the fatal overdose.

Prosecutor Zoe Fisher explained that Stillitano was driving Sutphin’s car when police pulled him over. He also had drugs in his pocket.

"Those tiny baggies had a red dice on them the same red dice pattern that are found in the trash can of Josh and Christie‘s home," explained Fisher.  

File: A red dice pattern on tiny baggies found both with Stillitano and in Sutphin's home were used as evidence in the trial.

A crime scene investigator testified that she found the baggie with the red dice patterns on it and collected it for evidence.

The medical examiner determined Sutphin died from a lethal mix of heroin and fentanyl, but Hillsborough Public Defender, Maria Dunker reminded the jury in closing arguments, that prosecutors couldn't prove the fatal dose came from Stillitano. 

Dunker pointed to cell phone records that show Sutphin was also buying drugs from other dealers. Dunker said the morning of his death he reached out to a drug dealer named David, but detectives never looked into it.

"No one reaches out to talk to David, no one looks at David's cell phone," argued Dunker. 

However, the jury did not buy that argument and convicted Stillitano. He will be formally sentenced on June 6, 2023.
