29-year-old David Andrew Bennett passed away over the weekend while in the Missoula County Jail where he was being held on an extra jurisdictional warrant and a Failure to Appear charge.

According to Missoula County Sheriff's Office Public Information Officer Brenda Bassett, Bennett is believed to have died on Saturday due to "medically related" circumstances.

An outside Sheriff's Department has been called in to investigate the matter and that process is still underway, so an exact cause of death is yet to be determined.

Because this was an in-custody death, procedure will bring in detectives from the Ravalli County Sheriff's Office to conduct  the investigation.
