A brazen thief rappels from the roof of a San Francisco car dealership, a celebrity chef's prized car is stolen, and a year later, a man in black opens fire on a young couple.

It was all a mysterious kaleidoscope of crime until last weekend, when investigators tied it all to a storage container in Richmond where they found a bright yellow Lamborghini and a teenager with a gun.

Now, there's a whole new mystery as investigators try to find out who this 17-year-old kid is, why he allegedly shot at two people in Mill Valley last month and what other crimes he may have committed. And, while they're at it, what the heck he thought he was going to do with a stolen $200,000 car.

The "Mission: Impossible"-style heist on March 8, 2011, at the exclusive Van Ness Avenue dealership baffled San Francisco investigators, who later that week spotted the car on surveillance cameras rumbling across the Golden Gate Bridge and breezing into wealthy Tiburon.

The convertible, known to car buffs as a Lamborghini Gallardo Spyder, was found Saturday in the possession of a 17-year-old San Rafael resident, who was allegedly keeping it in a rented Richmond storage locker.

The teen, whose name was not released, is also believed to be the motorcycle-driving gunman in black who opened fire last month on a couple sitting in a pickup truck in a quiet Mill Valley neighborhood.

"Our suspect in the shooting was found to be in possession of the vehicle," said Marin County Sheriff's Sgt. Mark Hale. "We're still trying to determine the source of where the vehicle came from and if there were others involved in the theft of that vehicle."

The suspect is being held in Marin County Juvenile Hall on suspicion of attempted murder and possession of the stolen Lamborghini. The Marin County district attorney is expected to file formal charges Tuesday, when prosecutors will also decide whether to charge him as an adult.

Crime No. 1

The strange tale began more than a year ago in the middle of the night when the daring thief climbed to the roof of the British Motor Car Distributors dealership, at 901 Van Ness Ave., attached a climbing rope and rappelled into the showroom.

The burglar ignored expensive Bentleys and Lotuses and selected the distinctive yellow 2008 model roadster owned by Guy Fieri, who stars in the Food Network on "Guy's Big Bite," "Minute to Win It" and "Diners, Drive-ins and Dives."

He then cut the lock to the dealership doors and brazenly drove off in Fieri's car. Except for the security camera videos that detectives viewed later that week, there had been no sign of the car.

Crime No. 2

Then, on April 13, a gunman wearing black clothing and a black helmet and riding a black motorcycle fired five shots at a couple in a pickup truck on the 100 block of Evergreen Avenue in Mill Valley.

The victims, identified by relatives as Landon Wahlstrom of Mill Valley and his date, a senior at Terra Linda High School in San Rafael, were cut by flying glass but were otherwise uninjured.

Wahlstrom, reached by phone, declined to comment about the motive for the shooting, but his uncle, Randy Wahlstrom, said he was told it was over a girl.

Landon Wahlstrom and the suspect had both attended Redwood High School in Larkspur. Wahlstrom's uncle said his nephew told him the suspect liked his female friend and took umbrage about something Wahlstrom apparently wrote on Facebook.

"Can you imagine a 17-year-old kid trying to kill two people?" Randy Wahlstrom said. "He's a live wire, and he meant to kill. It blows my mind. I don't know how none of the kids got hurt."

Lars Christensen, principal of Terra Linda High School, confirmed that the female victim was a student at his school and said he understood the suspect was in an independent study program outside the San Rafael school district.

"I don't believe she knew him well, but she knew who he was," Christensen said. "I know she was questioned. I don't know if that led to this other person's arrest or not."

As for her well-being, he said, "the assistant principal and I have been in touch with her and her family on multiple occasions. She's doing fine. She was remarkably composed and has remained so."

Stashed in Richmond

Hale said sheriff's investigators, acting upon information relating to the shooting, went to CSI Mini Storage at 855 Parr Blvd. in Richmond at about 7:05 p.m. Saturday. They served a search warrant on the teen's storage container and found the motorcycle and other items believed to have been used during the shooting, and Fieri's Lamborghini, which was still in good shape, Hale said.

The general manager of CSI, which has 2,000 storage units on 20 acres, said the 8-by-40-foot locker had been rented before the date of the car theft. The manager, who declined to be identified, said renters have to be at least 18 and show ID. Registration, a driver's license and proof that the car is running are also required for those who use the units specifically for storing cars, he said.

He wouldn't say whose name the unit was rented under.

"We're not at liberty to talk about the private matters of our clients," the manager said, adding that he had no idea the Lamborghini was stored there. "This is a very safe, secure facility. We are surprised."

Chef thanks authorities

Fieri, who in one of his shows explores classic "greasy spoon" restaurants around the country in his red 1967 Chevy Camaro SS convertible, thanked the Marin County Sheriff's Department and Mill Valley Police Department for helping recover his car, which can hit 60 mph in less than four seconds and is capable of topping 190 mph.

"I'm glad we can put this behind us, and feel better knowing that justice is being served," he said in an e-mail.

The suspect, who had a loaded handgun when officers arrested him at the storage center, was also booked for possession of a loaded firearm and resisting arrest.
