A Boise man is in the Ada County Jail, charged in connection with a man who was found dead in a vehicle in a west Boise parking lot Wednesday morning.

Tommy Basco, 29, is facing a felony charge of failing to notify a coroner or the police of a death.

Boise Police officers initially responded to a request for a welfare check on a man who appeared to be unresponsive in a vehicle parked in a parking lot near McMillan and Maple Grove Roads in west Boise.

Upon arrival, emergency personnel discovered that the man, later identified as 19-year-old Charles Chambers, was dead.

The Ada County Coroner has not yet determined the cause of death.

Boise Police detectives were able to locate evidence that another person, identified as Basco, had been aware of the circumstance, but failed to notify proper authorities, according to a Boise Police news release.

Detectives located Basco Thursday evening and transported him to the Ada County Jail.

At an arraignment Wednesday, prosecutors said after interviewing Basco, they believe Chambers overdosed on heroin when Basco attempted to revive Chambers my submerging him in ice water and then giving him methamphetamine.

Basco's bond is set at $100,000. His next court appearance is scheduled for Nov. 9.

The investigation is ongoing.

Detectives are continuing to look for others who may have information about the case. Anyone with information is urged to call Crime Stoppers at 343-COPS.

Charles' dad says his son graduated from Boise High School in 2015. His family has set up a donation account to help pay for funeral expenses.
