SF POLICE SHOOT AND KILL DOG THAT MAULED 2 MEN: SAN FRANCISCO (AP) — Authorities in San Francisco say one pit bull has been killed and a second captured after mauling one man and also injuring their owner.

Police say the incident occurred Tuesday night in Golden Gate Park after the dog's owner went to the store and left them with a friend near the park's entrance.

When the owner came back, one of his dogs attacked him.

After animal control and police arrived and could not corral the dogs Tuesday night, officers shot and killed one dog while the other dog ran away.

Animal Control officials say the second dog was captured Wednesday morning near the park. A hearing will be held to determine that dog's fate.

Authorities say the first man attacked is hospitalized in stable condition; the dog's owner refused treatment.

PASADENA POLICE KILL DOG, RESCUE MAN FROM ATTACK: Pasadena  (AP) — Pasadena police have killed a dog and wounded two others that attacked a bicyclist and trapped him on top of a car.

A police statement says Andrew Ross was walking his bike on a street around 5 a.m. Wednesday when the pit bull mixes charged across the street.

Ross says he tried to use his bike as a shield but one bit his leg, causing minor injuries.

Police say a witness reported seeing the dogs dragging a man.

Ross managed to break free and climbed onto the hood of a parked car.

Police say an arriving officer fired a shotgun as the snarling animals approached, killing one dog. Two wounded dogs fled but were later found and taken for treatment.

BOARD VOTES TO PUNISH CALIFORNIA STUDENT HACKERS: NEWPORT BEACH  (AP) — A Southern California school board voted after a lengthy late-night session to punish 11 students accused of hacking into computers at a wealthy public high school to access tests and change grades.

The Newport-Mesa Unified School District board deliberated for hours and emerged shortly after midnight Wednesday to announce it had decided to approve all the recommendations from administrators at Corona del Mar High School, the Orange County Register reported.

Many of those recommendations involve punishment that is less severe than an expulsion, but the district could not give further specifics on the discipline, citing confidentiality rules, according to the newspaper.

The students are suspected of hacking into computers with the help of a private tutor who has been missing since police searched his home on Dec. 18.

Under agreements approved by the board, the 11 students will be allowed to attend nearby schools in the district. They will also have their disciplinary records destroyed.

OAKLAND  BOY SURRENDERS AFTER SHOOTING OF SISTER: OAKLAND . (AP) — Police in California say a 14-year-old boy wanted in connection with the shooting death of his older sister has turned himself in.

Oakland police spokeswoman Officer Johnna Watson said Wednesday that the teen was accompanied by several family members, including his father, when he surrendered at Oakland police headquarters. Watson says he is being interviewed by detectives.

Police say the boy is suspected of fatally shooting his 17-year-old sister, who is the mother of a toddler, on Jan. 23 inside an apartment building in Oakland's Chinatown neighborhood.

The boy's father had publicly pleaded with the teen, who was considered armed and dangerous, to turn himself in. His surrender came after investigators spent hours talking to his family and friends.

LA PLANNING SAFETY CAMPAIGN AFTER 7 FIRE DEATHS: LOS ANGELES (AP) — The Fire Department and city leaders are urging people to install smoke alarms after seven fire-related deaths this month — an unprecedented number for a warm winter.

The department typically sees one or two deaths by this point in the year, fire Capt. Jaime Moore said, and that's during a chillier season when people are more likely to use space heaters and other appliances to keep warm.

"That's the irony of this," Moore said. "We've had seven fatalities without a cold spell."

All seven victims "died with no warning, due to no active, working smoke alarms in their homes," Battalion Chief Stephen Ruda said.

Fire officials also said residents should have a home-escape plan.
