COLUMBUS, Ohio -- Authorities have linked 12 shootings along a five-mile stretch of interstate around Columbus, including one that killed a woman and another that broke a window at an elementary school.
Four of the shootings — three at vehicles and one at the school last month — were from the same gun, Franklin County Sheriff's Chief Deputy Steve Martin said Tuesday.
Although ballistics tests could not link the rest of the shootings along Interstate 270, investigators said they "are comfortable" saying all 12 are connected, he said. He would not elaborate.
Authorities have received more than 500 tips, but would not speculate about who the shooter might be and would not release the type of weapon.
"Collectively, we think it's not good for us to put that information out," Martin said.
The shootings began in May along Interstate 270, the freeway that circles Columbus. Many were not reported until after Nov. 25, when 62-year-old Gail Knisley was killed by a bullet that pierced the side of a car driven by a friend.
The latest shooting linked to the spree was a Nov. 11 shooting at Hamilton Township Elementary School in Obetz, about two miles from the freeway.
Superintendent Bill Wittman said he believes the shooting was not meant to harm anyone because it happened overnight, but nervous parents expressed concern.
Tiffany Ellis, 32, said her son's second-grade classroom faces the front of the school, where the bullet struck.
"It makes me angry to be honest with you, that I have to drive down the road worrying about getting shot," Ellis said Tuesday.
She said she plans to call Wednesday to see what precautions the district is taking, and may avoid her own living room, which also faces the two-lane road.
"That's kind of scary to think someone could shoot through your window like that," Ellis said.
A house was shot at Tuesday near the freeway, but Martin said investigators have not linked it to the other shootings.
Local businesses have established a $10,000 reward for information leading to an arrest.
Criminal behavior experts have varying opinions on who's behind the attacks. Jack Levin, a Northeastern University criminologist, believes two people could be responsible.
"When I see a crime like this it's almost always two friends who probably wouldn't do this separately, but when they're together there's a certain chemistry, a certain insanity," said Levin, director of Northeastern's Brudnick Center on Violence.
"How do you share the joy of killing or causing problems if you're alone? You can't brag about it or someone will turn you in," he said.
But N.G. Berrill, a psychologist who profiles killers at his New York forensic consulting firm, said the shooter is probably a young male who feels frustrated and generally powerless in his life.
"It's almost an infantile rage is the way I would describe it," he said.
Berrill said the shootings were the work of a person who loves the thrill of causing panic, although he may not intend to kill.
The shooter is likely someone from the surrounding community, said Lou Palumbo, a retired police investigator who runs a private security and investigation organization called The Elite Agency Limited.
"He didn't have to travel far. He's got a certain comfort level with that landscape which could be what's allowing him to be drawn back to the same location of the shootings," Palumbo said.
Martin, the chief deputy, said investigators are not relying on a profile and are exploring all possibilities.
