ZION, Ill. - When the father of a missing 8-year-old found her bloodied body in a ravine, next to her lifeless best friend, it seemed every parent's worst nightmare.

Jerry Hobbs, just out of prison, led police to the girls himself. They wanted to know how he found them. They kept asking him questions. Finally, after hours of being interviewed, Hobbs was charged with both murders, a crime that stunned this small city near the Wisconsin line.

"I think its safe to say his reaction to questions piqued the officers' interest to question him further," prosecutor Michael Waller said in announcing the charges Tuesday.

Waller would not discuss possible motives for the killings but said details would come out when Hobbs appeared in bond court today.

"This horrific crime has terrorized and traumatized the Zion community and, I think it's safe to say, people of good will everywhere," Waller said. "There's no rational explanation or reasonable motive that can be ascribed to an act of horror like this."

Hobbs, 34, took authorities to the bodies just off a bike path early Monday, claiming he had spotted them while searching for his missing daughter with the girl's grandfather, Arthur Hollabaugh.

Hobbs was questioned through the day Monday and again Tuesday in the deaths of Laura Hobbs, 8, and Krystal Tobias, 9. Both girls had been beaten and stabbed multiple times and then left to die in the woods on Mother's Day.

The county coroner, Richard Keller, said the girls were found side by side, facing up and did not appear to have been sexually assaulted. They appeared to have been killed near where they were found, he said.

"If it was him, then good thing they brought him down," said Krystal's 15-year-old brother, Alberto Segura. "We never thought a father would do that to a daughter. They were just babies. They didn't do anything wrong."

Hobbs has an extensive criminal history dating to 1990 in Texas, including arrests for assault and resisting arrest, according to records kept by the Texas Department of Public Safety.

For the two years up until April 12, he was in a Texas prison serving time for assault involving an argument with Laura's mother, Sheila Hollabaugh, during which he grabbed a chain saw and chased neighbors through the trailer park where they lived, according to Rick Mahler, assistant district attorney for Wichita County, Texas.

No one was hurt in the 2001 incident and someone subdued Hobbs by hitting him in the back with a shovel, Mahler said. Hobbs was sentenced to 10 years probation but failed to appear for required meetings, so his probation was revoked in 2003 and he was imprisoned until last month.

Arthur Hollabaugh said Hobbs had been living with the Hollabaughs after his release. He said he worried authorities might be trying to railroad Hobbs in their search for the girls' killer.

"Jerry just got out of prison for aggravated assault, and I think they're holding that against him," Hollabaugh said before police announced charges against Hobbs. "I don't think he did it."

Hollabaugh described the search for his missing granddaughter and said he and Hobbs were in the woods shortly before dawn Monday when they spotted Laura's bike part way down a ravine in the brush.Minutes later, he said, Hobbs was screaming that he had found the bodies. "I went and I seen them from a distance," said Hollabaugh.
