Alan Michael Tanguay shivered and cried as he appeared before Judge Bruce Jacobus during Tuesday morning's court appearance. He was given a public defender and ordered to be held for 21 days, which is not unusual with juvenile offenders facing such charges.

The boy bragged about crimes long before the horrible murder and police said he even claimed he's murdered before. He told his friends that, so in addition to investigating the murder that took place, police have contacted authorities in several other states the teenager lived in to see if he committed other murders similar to the one here.

After a pre-dawn raid on the teen's Palm Bay home, Alan Michael Tanguay was led away to jail, arrested for allegedly killing 58-year-old Patricia Kaliszeski in one of the bloodiest murders detectives can remember. His neighbors couldn't believe he was responsible.

"To guess that he would do something like that, I wouldn't think so, but people are funny," neighbor Conrad Dufault said.

On 911 tapes released Monday afternoon, Kaliseski's ex-husband described finding her body.

"It looks like there is blood all over the place," he said.

Police said the high school dropout spent his days smoking marijuana, drinking beer and playing violent video games.

"I like gory (expletive), like people getting their neck slit and tounge (sic) pulled out," Tanguay wrote on his MySpace page.

Investigators said Tanguay walked to the woman's house and followed through with a personal rule that he would kill the homeowner if they caught him burglarizing their house. Police said he stabbed Kaliszeski multiple times, but during his confession said he was trying to ease her suffering when he nearly decapitated her.

"He knew she was going to die, so to keep her from suffering any more he went ahead and cut her throat to have her die more quickly," explained Det. Ernie Diebel, Palm Bay Police Department.

Tanguay began bragging to friends before the body was discovered and, once they learned he wasn't joking, they turned him in.

"There's no doubt in my mind he would kill again," said Chief Bill Berger. "I'm extremely proud of our team that worked round-round-clock to make the arrest as quickly as possible. This individual is a self-proclaimed psychotic killer and what he did to this victim is beyond words. He needs to be locked up for the rest of his life."

Police said Tanguay told his friends precise details about the crime that only the killer would have known and showed them his batting gloves he wore and the Vans tennis shoes that left the Vans imprint in the blood stains on the floor of the house.

Investigators said Tanguay stole around $6 and that he intended to use it to purchase beer.
