COLUMBUS Freeway shooting evidence links only 2 cases, police say

Police have received about 250 tips about the case.
COLUMBUS (AP) -- Tests on bullet fragments could not link more than two of 11 shootings along a 5-mile stretch of a highway circling the city, the Franklin County sheriff's office said.
The two were "a definite match," but not enough evidence was recovered from similar shootings in the area to find further matches, Chief Deputy Steve Martin said Saturday.
"Everything we have has been tested."
On Friday, police said a shooting that killed a 62-year-old woman -- the only person hit by a bullet -- wasn't accidental and is linked to at least one other case.
One or more people are deliberately targeting drivers, but he still refuses to use the word "sniper," Martin said. The term evokes an image of a person with military training lying in wait in the woods while wearing camouflage, he said. This shooter could be mobile, he said.
A task force investigating the shootings has received 250 tips, many naming suspects, Martin said. Police have interviewed people but have not taken anyone into custody for questioning, he said.
The shootings
The shootings on or around a southern section of Interstate 270 began in May. The shots have been fired at different times of day, piercing trucks, cars, vans and pickups, shattering windows and flattening tires.
Gail Knisley, a passenger in a car on I-270 who was killed Tuesday, was buried Saturday in her hometown of Washington Court House, about 40 miles southwest of Columbus.
Martin declined to speculate on the type of weapon, saying it could harm the investigation.
"We have some ideas, but we're not going to discuss those issues," he said.
