"There's really no specifics that I can let out on this, just through the specific dynamics of this case," said Sgt. Shan Davis of the Beverly Hills Police Department. "It's very unique, and eventually, these specifics will come to light."
Davis said police were able to work off of good leads.
"This was good, old fashioned police work of detectives just literally working 24 hours to get these individuals into custody," he said.
Authorities responded to the 1800 block of Carla Ridge in the Trousdale Estates area after receiving a 911 call about unknown trouble at 6 a.m. Tuesday. They found the body of 21-year-old Katsutoshi Takazato, who was declared dead at the scene.
"We're talking about a murder investigation here, and the sheer collection of evidence may take 12, 15 hours," Davis said. "Blood splatter, DNA evidence, some of the smaller things to clothing that may be discarded as the suspect flees."
Lt. Cheryl MacWillie of the Los Angeles County coroner's office said the victim lived at the home. The home is owned by Fuminori Hayashida, a movie producer that has made films with Christian Slater and Dennis Hopper.
Directly across the street from the crime scene is the home of Sherwood Schwartz, the legendary TV producer, and his wife, Mildred.
"I can't get over that they caught the three of them already," Mrs. Schwartz said. "The police called me to inform us that we don't have to worry, that everything was taken care of. We are very happy not to worry now."
On the streets surrounding the crime scene, residents were stunned to learn that a young man had been stabbed to death in the upscale neighborhood.
"It's alarming when you're trying to walk your dogs in the morning and the police say to you, 'Go in your house and lock your doors and close your windows," said neighbor Iann Weiss.
According to friends and neighbors, Takazato was living alone in the house.
"He was a great guy" said the victim's friend, Arthur Brandalis, who described him as kind and generous. "I don't understand how something like this can happen to him. He does not deserve it."
A motive for the killing has been not been determined.
