On October 11, 2006, law enforcement officials said that blood spatter had been found in Hans Reiser's house and car. Forensic testing (including DNA analysis) could neither confirm nor rule out Nina Reiser as the source of the blood. Officials had not located the missing passenger seat of his car. They also indicated that they had found in the car two books on homicide investigation purchased by Reiser on September 8 — five days after his wife's disappearance: "" by David Simon, and "Masterpieces of Murder" by Jonathan Goodman. Daniel Horowitz, a high-profile defense attorney, joined the defense team but dropped the case on November 28, citing Reiser's inability to pay for his services. Namesys's employees stated that Reiser felt that the police would suspect him from the start. Reiser was arraigned on Thursday, October 12, where he delayed entering a plea until his next court appearance on November 28. He was held without bail. On November 28, Reiser entered a not guilty plea and invoked his right to a speedy trial, forcing the state to schedule a preliminary hearing for December 11.
