MIAMI -- A trial date has been set in the case over the killing and mutilation of 19 cats in Miami-Dade County. Tyler Weinman, 18, faces 19 counts of felony animal cruelty, four counts of burglary and 19 counts of improper disposing of an animal's body. Weinman is accused of killing 19 cats in the Cutler Bay and Palmetto Bay areas. He was arrested on June 14. The teen has pleaded not guilty to the charges against him. His lawyers said the evidence is circumstantial and lacking witnesses. The trial has been set to begin on Oct. 19. Weinman will remain on house arrest until the trial. Surgical tools among items seized in cat killings case BY DAVID OVALLE [email protected] Scalpels, knives, nylon rope with duct tape attached, computers, cameras and clothing were among items seized by detectives investigating alleged cat serial killer Tyler Weinman, according to court documents released Friday. Weinman is accused of killing 19 cats in South Miami-Dade between April and June in a spree that shocked pet owners and prompted a highly publicized police probe. A trial is set for October. The circumstantial case may ultimately hinge on what forensic evidence such as blood, hair and DNA can be linked to the cat killings. Miami-Dade detectives searched houses and cars belonging to Weinman's divorced mother and father, Douglas Weinman, a dentist who owned various dental tools. The teen lived with both. From the elder Weinman's home, investigators took the most items, including a wooden spear gun, more than a dozen cutting and dental tools and electronics. From his father's car, which detectives believe Weinman drove during the killings, investigators took everything from floor mats to gloves. Detectives are also examining Weinman's boxer briefs and other articles of clothing found in a black plastic bag in the trunk of his mother's green Volkswagen Passat. Police believe she was removing the items from the house when detectives arrived. Weinman's attorney, David Macey, appeared in court Friday to ask that investigators return property belonging to Weinman's family such as business equipment and tax returns. Prosecutors are still working to sort out what evidence will not be used as evidence against the teen. Weinman has pleaded not guilty and is on house arrest pending trial.
