A jury convicted the main suspect in metropolitan Phoenix's Serial Shooter attacks of murdering six people, but acquitted him in two other killings.

The convictions on Friday bring to a close the first phase of the trial of Dale Hausner, a former janitor who is also accused of attacking 20 other people, seven dogs and three horses.

Prosecutors are seeking the death penalty against Hausner. The trial's penalty phase begins March 23.

Police said Hausner, who denied any involvement in the attacks, shot at people from his car during 2005 and 2006 in a conspiracy that occasionally included his brother and a former roommate, Samuel Dieteman.
