Report details gruesome attack on 15-year-old found dead in vacant lot
Las Vegas, NV (KTNV) -- The police report released after the arrest of Javier Righetti details the gruesome fatal attack on 15-year-old Alyssa Otremba.
Otremba's mother said she received a text message from her daughter on Friday evening while Alyssa was walking home on Grand Teton. Alyssa told her mom she'd be home in about 30 minutes, but never returned.
Alyssa's mother called police to report her daughter missing after searching the area to find her and calling her several times.
Police looked for the 15-year-old, but couldn't find her.
On Saturday, family and friends were searching for Alyssa when a body was discovered in a vacant lot south of her home.
The body was badly burned to the point of being unrecognizable, according to the police report.
Detectives were called to the scene and authorities immediately began searching the area.
On Monday, the Clark County Coroner's Office performed an autopsy, confirming what many had suspected- that the body was that of Alyssa Otremba.
According to the coroner's report, the body had more than 40 stab wounds to the face, neck, chest, stomach and thighs. The body had been burned using an accelerant.
On Monday, an acquaintance of Alyssa called police with details on the murder. She met with police and told them her boyfriend, Daniel Ortiz, had been receiving several calls from a friend, Javier Righetti, on Friday night.
Police contacted Ortiz at his workplace later on Monday, where he agreed to give a statement on Javier Righetti.
Ortiz said Righetti had called him at about midnight saying he needed help, and Ortiz went to meet him at his house.
Ortiz said Righetti told him he had committed several robberies and then killed a girl in a deserted area. Ortiz didn't believe the story, and assumed Righetti was high on drugs.
Righetti asked for a ride, so Ortiz drove him to the Albertson's Express on Durango, where he bought matches and gasoline. He put the gasoline in a can he'd brought from his house, Ortiz told police.
Ortiz then drove Righetti to an empty lot on Osa Blanca Road. They both got out of the car, with Righetti carrying the gasoline and a small duffle bag.
Righetti asked if Ortiz wanted to come with him to the vacant lot where Alyssa's body was later located.
Ortiz told police he told Righetti he thought he was going to throw up, and drove off in his car, avoiding Righetti's calls from then on.
Ortiz and his girlfriend identified Righetti's residence as 7964 Willow Pines Place.
Metro police executed a search warrant at the house on Monday night. Righetti surrendered to officers and was taken to the homicide office by police detectives.
At the office, Righetti confessed to stalking Otremba, attacking her and robbing her. He also confessed to raping her and stabbing her to death with a kitchen knife from his house.
Righetti said he burned the body with the gasoline to destroy the evidence.
He also said it isn't the first time he's committed robbery and rape. Police are now investigating a second unrelated incident of crimes involving Javier Righetti.
Righetti was taken to the Clark County Detention Center by detectives.
He was booked for kidnap, robbery, sexual assault and murder with a deadly weapon.
