A .22 caliber handgun was used in the murders of Valerie Wilson and
Greg Giblin. A different weapon was used in each of the killings. Markings
from the gun barrel appear on the bullet, leaving a unique fingerprint.
A
voluntary search of the Knight residence turned up a handgun inside
a toolbox. The weapon, a .22 caliber model, is manufactured by Heckler
and Koch. It is registered to Frank
Knight. There is no indication of recent firing. Internal ballistic
testing showed no similar barrel scoring or patterning matching the
weapons found at the Giblin and Wilson shootings. |
