Police records show that a Texas man accused of killing two people while randomly firing his gun along an Oklahoma interstate last month may have fired nearly 30 times.

The Oklahoman newspaper reports (http://bit.ly/1UX9FC6 ) that investigators said they found 28 shell casings inside Jeremy Doss Hardy's pickup, as well as a gun holster, an empty pistol magazine, a magazine pouch, five rounds of ammunition in a magazine and one loose live round.

The Pasadena, Texas, man has been charged with first-degree murder.

Police have said Hardy sped through three counties while firing from his pickup along Interstate 40, west of Oklahoma City, and hit at least four vehicles.

The first victim, a 45-year-old man, was traveling with his wife, who wasn't struck. The second victim was a 63-year-old.
