Newly released court documents indicate that the man who went on a deadly rampage with an AK-47 at a Nevada pancake restaurant last week had been diagnosed as a schizophrenic.
Douglas County sheriff's Sgt. Mark Munoz told the Carson City Justice of the Peace in an affidavit on the day of the shooting that Eduardo Sencion's sister-in-law told investigators that the man had been taking medication for his illness, and that he may have been the driver of a blue 2002 Chrysler minivan found parked outside the IHOP restaurant.
The information about the man's mental state came to light as investigators sought search warrants for Sencion's two vehicles and the homes of his parents and brother in the chaotic hours after the shooting spree.
The Nevada Appeal reported Wednesday that recordings of the oral affidavit were unsealed Monday.
Carson City sheriff's Detective Dave LeGros didn't immediately respond to a message Wednesday from The Associated Press.
Five people were killed in the shooting at the IHOP not far from the Nevada Capitol, including Sencion and three Nevada National Guard members. Seven people were wounded.
LeGros told the court that officers wanted to search the homes and vehicles for weapons, ammunition and other items possibly linked to the deadly rampage.
LeGros said officers feared they might find more victims at the family home, but they found Sencion's sister-in-law unharmed. Two children were also in the home and not hurt, and their identities are not known.
The sheriff's investigator said investigators were also seeking "electronic storage devices which may possess a type of memoir or reason why this terrible act occurred."
The woman told the investigators that Sencion lived there for almost three years before moving earlier this year to his parents' home.
Officers found no one home at the parents' house, but reported finding more firearms and "boxes upon boxes" of ammunition suitable for an SKS or AK-style weapon.
Detectives have not yet filed with the court a list of the evidence collected from the scenes.
