Tonia Bohlke hired a private investigator to probe the death of her husband, Bill Bohlke, 65, whose body was found at his ranch in August 2012.
Police concluded the Hollywood Park mayor had been trampled to death by a stud donkey, but an investigator hired by Tonia Bohlke found the cause of death was inconclusive, the San Antonio Express-News reported Saturday.
"There are too many inconsistencies for an alleged animal attack to have caused Mr. Bohlke's injuries and death," Dr. Gary Deegear's report states. "The patterned injuries, the boot prints, and the lack of expected evidence are enough to warrant further investigation into this matter."
Attorney Edgardo Baez said he hopes to have the body exhumed and the case reopened.
But Atascosa County Sheriff David Soward said that will not happen.
"There was no murder, there was no evidence of murder and never any new evidence of murder," he said
Baez said Bohlke had plans to meet with two men on the day of his death to sell them a bull. They were never interviewed and an autopsy was never conducted.
"This has been horrendous for them," Baez said of the Bohlke family. "His wife has been non-stop searching for clues. It has been nightmare after nightmare."
