FBI investigating case of Florida man accused of making death threats against Tyler Trent's family

The FBI is now investigating the case of a Florida man accused of making death threats against the family of a Purdue University superfan and cancer activist who died last week.

Volusia County Sheriff Mike Chitwood tells The Daytona Beach News-Journal that 39-year-old John Pinkham will be extradited to Indiana to face federal charges of intent to injure. He was arrested Monday.

Chitwood says Pinkham denied sending the threats and blamed his girlfriend.

Trent's battle with bone cancer drew national attention.

A lawyer for Pinkham isn't listed.
