COLUMBUS, Ohio (AP) – Two more shootings have occurred in the Columbus area since a woman was killed as she traveled to a doctor’s appointment, bringing the number of cases under investigation to 14, authorities said Friday.

One of the shootings was at a car on Sunday on Interstate 270, Franklin County sheriff’s Chief Deputy Steve Martin said.

The other shooting was at a house sometime between Sunday and Monday, Martin said. The homeowner found a bullet hole in front of her house and recovered a bullet from living room floor, Martin said.

No one was injured in the shootings.

Police believe the shootings are the first since Gail Knisley was killed Nov. 25 on I-270.

“Investigators now know the person or persons has consciously decided to continue with the same activity which unfortunately resulted in the death of Mrs. Knisley,” Martin said.

The bullet from the house came from the same gun as four other shootings that have been definitely linked by ballistics tests, including one at a school, Martin said.

Although the tests could not link the rest of the shootings, investigators believe they all are connected.

The addition of the house shooting expands the investigation area east by two miles, with the police now examining a seven-mile section of the freeway.

A trucking association has asked drivers to report anything out of the ordinary to law enforcement as authorities try to solve the shootings. The American Trucking Associations sent the alert this week to drivers, who can use a toll-free number that links them with law enforcement.

In the Washington-area sniper shootings case, a truck driver was credited along with another man with tipping police to the suspects’ location.

“He saw an alert to truck drivers on the news. We have about 30,000 members who can act as eyes and ears on the road,” said truckers association spokesman John Willard.
