A Las Vegas man shot himself in the head and died after a 90-mile chase in a stolen car. Police said the victim, 22, and his 18-year-old brother were spotted on Interstate 15 after they stole a red Ferarri sports car from a leasing firm in Las Vegas. Officers pursued them at speeds sometimes exceeding 100 m.p.h. across the border into California, where they were finally cornered near Baker. As officers approached, they said, the elder brother fired a single shot into his head. His name was withheld, as was that of the younger brother, who was held in Baker as a fugitive and on suspicion of possessing a stolen car. "It was apparently some kind of suicide pact the two brothers made when their business went under," San Bernardino County Sheriff's Sgt. Al Perea said. "Both of them had .25 automatics. One used his; the other didn't."
