Lincoln-Way East defensive end  Devin O'Rourke  knew the significance of stopping Homewood-Flossmoor from scoring on its first series of the second half.
With  O'Rourke  leading the charge  East forced H-F into a three-and-out and the offense responded with two straight scores for a 29-7 SouthWest Suburban win in Flossmoor.
"The defense knew it had to stop them "  O'Rourke  said. "We did that and the offense came up with the score. This is the best defense I've played on."
The 6-foot-6  250-pound  O'Rourke  not only was a force on defense  the Northwestern recruit provided the offensive line with some firepower when he substituted in at right tackle.
 O'Rourke  hadn't played on the offensive line since his freshman year. He's more than willing to step in when needed.
"I'm used to attacking on defense "  O'Rourke  said. "It's been a little different blocking. It's a little tiring going both ways  but it's fun when we score and celebrate."
Max Cesario  Sam Broda  Dylan Shelton and  O'Rourke  had seven tackles each for the Griffins. Shelton   O'Rourke  and Pedersen recorded sacks.

 Papini  disappeared Nov. 2 while jogging near  her  home in Shasta County  about 215 miles north of San Francisco.
 Her  husband found  her  phone and earphones near their home after  she  failed to pick up their children at daycare and called police. He was initially a suspect  but the sheriff said Wednesday that the husband passed a lie detector test and offered to take another.
Authorities also said a Detroit man Papini texted and planned to meet shortly before  her disappearance  has been cleared of involvement.
 Papini  was found alongside Interstate 5 in Yolo County  about 100 miles from  her  home.  Her  nose was broken and  she  was wearing a chain restraint around  her  waist.  Her  blonde hair had been cut to shoulder length and  she  had a "brand" burned into  her  right shoulder.
Investigators declined to discuss the "brand" in detail.  Papini  has said  she  was not sexually assaulted and has described  her  abductors as two women who took  her  at gunpoint.
Sheriff's Sgt. Brian Jackson said the sketches drawn by FBI artists are being released 10 months after  her disappearance  because of  Papini 's difficulty in recalling what  her  abductors looked like.

FBI spokeswoman Sandra Berchtold said she could neither confirm nor deny how the militia groups helped the FBI.
But a University of Michigan graduate student who is studying the militia movement said she was aware of the contact between the two and said she saw e-mails from the militia to the FBI about the Hutaree. She declined to say who wrote those e-mails.
The student  Amy Cooter  who has interviewed dozen of militia members  said she steered clear of the Hutaree in part because of safety concerns.
She said she isn't surprised the militia alerted the FBI. The Hutaree was advocating a distrust of law enforcement  she said  that doesn't match the beliefs of most militia members. "I could tell they weren't representative of the other militias in the state " she said.
