Johnson County resident Troy Gene Prine committed suicide Tuesday afternoon, Johnson County Sheriff Bob Alford said.
Prine was arrested on several charges of pornography and sexual assault In Johnson and Hill counties.
Prine was due in court in Hillsboro on Tuesday, Alford said.
He apparently told his girlfriend he was going to end it all and to let him out of the vehicle while traveling to court, Alford said.
The girlfriend called 911 and deputies arrived to find Prine dead.
The Hill County Sheriff's Office contacted the Johnson County Sheriff's Office with the news about 3 p.m. Tuesday, Alford said.

Prine was arrested in October on charges, filed by the Texas attorney General’s Office, of possession of child pornography and improper photography. After investigations, Prine was also charged with four counts of indecency with a child through sexual contact.
When he was arrested, officials said Prine, 42, lived in Grandview. Later information said he had a Cleburne address.
Prine was arrested Oct. 1 by deputies with the Johnson County Sheriff’s Office, working with the Texas AG’s Cyber Crimes Unit. Prine was targeted after the Attorney General’s Office received a tip from the National Center for Missing and Exploited Children.
Officials with the Rio Vista Volunteer Fire Department confirmed that Prine had been a volunteer with the department, but said that he had not been active as a volunteer firefighter for several years.
Prine was indicted Nov. 21 on a charge of sexual assault of a child, in connection with an offense that occurred Aug. 1. He was free on a total of $250,000 bond.
