Bond was set at $4 million on Thursday for the gunman who killed one and wounded three outside of a Texas courthouse Wednesday, the Houston Chronicle reported.

Bartholomew Granger, 41, is currently in custody at Jefferson County Correctional facility, 85 miles east of Houston, on murder and aggravated sexual assault charges.

Granger allegedly began his shooting spree around 11:30 a.m. at the Jefferson County Courthouse Wednesday just before his sexual assault trial was set to resume. Granger fired his first shots at relatives scheduled to testify against him while they were standing near the entrance of the courthouse.

Granger's bullets connected with three, killing one: 79-year-old innocent bystander Minnie Ray Sebolt.

Granger's other victims were his estranged wife and an unnamed Hispanic woman with no connection to the trial.

Both his wife and the Hispanic woman were treated and released from a local hospital. Authorities did not release their names.

The gunman then shot his daughter and ran over her in his pickup truck in the courthouse parking lot.

Three-million dollars of his bond was for his murder charge with the remainder for the aggravated sexual assault count

The daughter, identified as 20-year-old Samantha Jackson, remained in critical condition Thursday.

According to FOX News, Jackson was the child Granger allegedly sexually assaulted.

Jackson began testifying against Granger on Tuesday and was scheduled to resume her testimony Wednesday afternoon. Granger's estranged wife, who is also Jackson's mother, was also scheduled to be a witness for prosecutors.

Authorities said Granger's shooting was motivated by a longstanding family feud over the sexual assault allegations.

Granger's brother, Ulysees Granger, told the Chronicle he talked with his sibling Wednesday morning.

"He said, 'My head is so messed up I can't even think straight,'" Ulysses Granger said. "He said he was going to clear his head. He hugged me, kissed me on the cheek and left. He was stressed. This has been going on for 15 years."
