Phoenix police have identified a second case that the brother of one of the accused serial shooters may be involved in. On Tuesday, police said Jeffrey Hausner, brother of Dale Hausner, stabbed 35-year-old Timothy Davenport in a west Phoenix parking lot. Around 6 a.m. on May 17, 2006, Davenport was stabbed repeatedly in the back and left side in a parking lot at 4827 N. 75th Ave. Jeffrey Hausner is serving a 7  1/2-year prison term for the stabbing of a homeless man on April 14, 2006. That case has not been linked to the serial shooters' killing spree. Dale Hausner and Samuel Dieteman were arrested in August 2006 at their Mesa apartment. They are charged in connection with a monthslong spree of violence across the Valley that left eight people dead and 14 others wounded. Authorities allege that the pair drove around Phoenix, Mesa and Scottsdale and shot people and animals at random with a shotgun. Dieteman has pleaded guilty to two murders and has agreed to testify against Dale Hausner, who faces eight murder charges and has pleaded not guilty. Investigators believe that Dale Hausner and Dieteman were with Jeff Hausner during the stabbing of Davenport. The case was submitted to the Maricopa County Attorney's Office for prosecution, and Jeffrey Hausner is now facing charges of attempted murder in that stabbing. Jeffrey Hausner has also been linked to another shooting police say involved his brother and Dieteman. That one was in November 2005 and involved the killing of Nathaniel Schoffner, a transient who tried to intervene to stop the men from killing a dog in Phoenix.
