The FBI has taken over the case of a Deltona man who Volusia County sheriff's deputies said made Facebook death threats toward the family of Purdue University super fan and cancer activist Tyler Trent, Sheriff Mike Chitwood said Wednesday.

John Matthew Pinkham, 39, was arrested Monday and charged by Volusia deputies with written threats to kill and do bodily harm after Indianapolis Metropolitan Police said he threatened Kelly and Tony Trent on the comment section of their son's Facebook page the day before Tyler Trent's funeral.

Pinkham was being held Wednesday at the Volusia County Branch Jail on $10,000 bail and will be extradited to Indiana to face federal charges of intent to injure. The Volusia County charges will be dropped because the FBI has taken over.

"Pinkham was served today with a federal arrest warrant at the jail and will be taken tomorrow to Seminole County," Chitwood said Wednesday. "There he will be arraigned and then he will be extradited to Indiana to face charges for what he did."

Volusia investigators said Pinkham posts to the Facebook page threatened that he would shoot up Tyler Trent's Celebration of Life Ceremony, Chitwood said.

That ceremony was held Tuesday in Indiana.

Chitwood said Pinkham denied sending the written threats and blamed his girlfriend for them.

Investigators pinged the telephone number given to them by Indianapolis police and traced it to Pinkham's Deltona home. When they got to the home, they found the cellphone in Pinkham's pocket, Chitwood said.
