Seven months after an arrest, the entire case against a suspect in a series of freeway shootings that rattled Phoenix residents fell apart.

Leslie Merritt's arrest, the entire case fell apart, leading to his release, the dismissal of charges, allegations of a botched investigation and a gunman authorities dubbed a domestic terrorist possibly still on the loose.

Police believe the shootings began Aug. 27 and continued until Sept. 10. Investigators determined eight of the incidents were bullet strikes while the remaining three were some other projectiles.

A DPS crime lab found a match between bullets from four shootings to a gun belonging to Merritt.

But a forensics expert hired by the prosecution re-tested the bullets found the lab had come to a faulty conclusion.

DPS Director Frank Milstead, however, said Friday that he believes there is enough evidence to show Merritt is the correct suspect.
