EAST PEORIA — An off-duty FBI agent may have averted a mass-shooting Saturday night when a gunman walked into a sports bar packed with patrons attending a high school reunion and shot his ex-wife and her new boyfriend. 
  
 The gunman was killed when the agent, whom police would only officially identify as an off-duty law enforcement officer and subsequently asked not to be named, shot the suspect after gunfire erupted about 8 p.m. at the Fifth Quarter Sports Bar and Pizzaria. 
  
 The suspect and the two targets of his initial burst of gunfire ultimately died — the suspect at the scene and the other man and woman at a Peoria hospital. 
  
 East Peoria Police Chief Dick Ganschow said investigators were reviewing video of the incident recorded at the bar, and crime scene investigators were gathering evidence. Interviews of friends and relatives of the shooter and the victims will continue in the coming days to determine the background that led to the deadly shooting. 
  
 Lori A. Moore, 33, of Morton was pronounced dead at 9:16 p.m. at OSF Saint Francis Medical Center, according to Peoria County Coroner Johnna Ingersoll. Moore had a gunshot wound to the head, the coroner said. 
  
 The man who was transported to the hospital was pronounced dead at 9:39 p.m., also from an apparent gunshot wound to the head. He was a 36-year-old Peorian, but his next of kin could not be immediately located and his name was not released. 
  
 Autopsies for the pair will be scheduled for Sunday or Monday, Ingersoll said. 
  
 Moore filed for a divorce from Jason A. Moore in Peoria County in March 2013, according to court records. The dissolution of marriage and parenting agreement were final in May 2013. 
  
 The shooting incident happened about 8 p.m. Saturday at the establishment at 1110 N. Main St., just across Illinois Route 116 from the Par-A-Dice Hotel and Casino. A heavy police presence remained on scene for hours after the gunfire erupted. 
  
 “After just a brief moment inside the bar, he pulled out a weapon and shot a female and a male,” Ganschow said of the suspect. “He was subsequently shot.” 
  
 Multiple sources, including a person at the scene who declined to be identified, said the shooter was the ex-husband of the woman who was shot. The other male who was shot was the woman’s new boyfriend. They were attending a high school reunion. 
  
 A group of people on motorcycles wearing regalia of the Outlaw Motorcycle Club left the bar immediately after the shooting and was followed by police to a clubhouse on Farmington Road in Peoria County. Police later said they were witnesses to the incident, and not suspects. 
  
 Dozens of police and other emergency response vehicles blocked the portion of Main Street that led from the entrance to a Shell gas station at the Route 116 intersection to the sports bar. 
  
 A crowd of onlookers gathered on the other side of Route 116 and near the entrance of the gas station, where police strung yellow crime scene tape from the side of the building to prevent witnesses from leaving the sports bar parking lot. A couple tearfully embraced over the tape, and police later lifted the yellow cordon to allow vehicles to depart one-by-one.

 Within seconds, an off-duty law enforcement officer at the scene jumped into action, firing his weapon, killing the suspect. 
  
 According to the Peoria County coroner, the female victim is Lori A. Moore, 33, of Morton, Ill. She was pronounced dead at OSF St. Francis Medical Center at 9:16 p.m. Saturday. 
  
 The male victim is Lance E. Griffel, 36, of Peoria, Ill. He was pronounced dead at OSF St. Francis Hospital at 9:39 p.m. Saturday. 
  
 Both victims were shot in the head, according to the coroner. 
  
 Authorities say the incident occurred around 7:50 p.m. at The Fifth Quarter Sports Bar and Pizzeria, located on North Main Street, across from the Par-a-dice Hotel and Casino. 
  
 East Peoria Police Chief Dick Ganschow says the slaying is domestic violence related, identifying the deceased suspect as the ex-husband of Moore. 
  
 According to court records, Moore filed for divorce from Jason A. Moore in March of 2013. It was finalized in May of 2013. 
  
 Witnesses say East Peoria Community High School Class of 1999 was holding its class reunion at the bar at the time of the shooting. Beyond the 3 individuals who were shot and killed, no other injuries were reported. 
  
 Numerous law enforcement agencies responded to the initial call of shots fired including East Peoria Police, Fondulac Park District Police, Creve Couer Police, Tazewell County Sheriff's Department and Illinois State Police. 
  
 Chief Ganschow said because this was a law enforcement officer involved shooting, Illinois State Police would be taking the lead in the investigation. 
  
 Chief Ganschow declined to identify the officer and agency involved in the shooting, citing an ongoing investigation. Special Agents from the FBI were also on the scene Saturday night. |||||
Output:
A high school reunion in East Peoria, Illinois, turned tragic Saturday night when the ex-husband of one of the attendees stormed in with a gun, killing his ex-wife and her new boyfriend, police say. James Moore, 40, was then himself fatally shot by an off-duty law enforcement officer, the Peoria Journal Star reports. Moore shot Lori Moore, 33, and Lance Griffel, 36, once each in the head, inside the crowded Fifth Quarter Sports Bar and Pizzeria around 8pm. The Moores' divorce had been finalized in May of last year. Some of the patrons belonged to the East Peoria High School class of 1999; ultimately, more than 100 witnesses spoke to police. "You can play the 'what if' game over and over again, but I think it's pretty clear in this case the presence of this officer and his ability to take very quick and very decisive action prevented a further tragedy," said the police chief of the off-duty officer. An earlier Journal Star article identified that officer as an FBI agent, and WEEK-TV noted special agents from the FBI were present at the scene.
