Shark Kills 19-Year-Old Man Off Beach on Vandenberg Air Force Base

(CNN) -- A shark attack Friday killed a 19-year-old college student off a beach on Vandenberg Air Force Base, said authorities in Santa Barbara County, California.

A shark, described as being 14 to 20 feet in length, bit off the left leg of Lucas McKaine Ransom of Romoland, California, while he was Boogie Boarding with a 20-year-old male friend, said a spokesman with the Santa Barbara County Sheriff's Department. Ransom was a junior at University of California at Santa Barbara. He was majoring in chemical engineering.

On Friday morning, Ransom was riding the waves at Surf Beach about 100 yards offshore when a shark pulled him under the water, authorities said. His friend and other witnesses pulled him from the water, authorities said.

Authorities released a photograph of the Boogie Board, showing a 13-inch bite mark.

Air base fire personnel pronounced Ransom dead at the scene.

Federal and state fish and game officials are trying to identify the type of shark.

Surf Beach is one of three that sit on the coastal military base, and officials closed all three beaches at 9:46 a.m. Pacific (12:46 p.m. ET), shortly after the shark attack, an air base spokesman said.

"Our first responders were on scene to assist in rescue efforts," Col. Richard Boltz, 30th Space Wing commander, said in a statement. "Our thoughts and prayers go out to the family and friends."

The three beaches will remain closed for 72 hours, the spokesman said.

Surf Beach is open to the public, but the other two -- Wall and Minuteman beaches -- are open to base personnel only, the spokesman said.

The Santa Barbara County Parks Department is posting warning signs at beaches in the Jalama and Guadalupe beach areas, authorities said.

13,500 Flee Growing California Wildfire

Really getting serious over there.. =[

SANTA BARBARA, California (CNN) -- A wind-fanned wildfire spread across 1,300 acres in Santa Barbara County, California, early Thursday, forcing 13,500 residents to evacuate and destroying at least 20 homes.

The fire, strengthened by high temperatures and low humidity, engulfed mansions in the coastal community's foothills.

"It's just horrible. We're all in a panic here. It's terrifying," iReporter Exton Quinn said Thursday.

Quinn said she and a friend were out shooting video Wednesday night when "all of a sudden the wind changed and a house caught on fire just behind me," she said.

Her house, on the edge of the mandatory evacuation zone, hadn't burned, she said, but the artist and architect said she was concerned as she headed for Los Angeles on Thursday morning.

More than 1,400 firefighters are battling the blaze and 10 have been injured, Schwarzenegger said, lauding their efforts. Watch Gov. Schwarzenegger urge vigilance »

"Firefighters, thank you, thank you, thank you for your hard work," he said.
A day earlier, fire officials expressed how difficult it is to fight the blaze.

"The fire is moving very, very rapidly," Santa Barbara County Fire Capt. David Sadecki said Wednesday. "This is an uncontrolled wildfire."
"I have hundreds of paintings, so I would just lose everything," if her duplex did fall victim to the flames, she said.

About 5,400 homes have been evacuated and another 3,500 are threatened, California Governor Arnold Schwarzenegger said at a news conference.

The blaze, which started Tuesday, came six months after the Tea Fire destroyed about 200 homes in the Santa Barbara area.

Though there was no official count on homes destroyed early Thursday, one firefighter said he saw 20 homes scorched.

Firefighting helicopters and aircraft as well as 177 engines were being used.

On Thursday morning, iReporter Adrian Casillas, a student at the University of California-Santa Barbara, said it felt more like evening.

"I'm looking out towards the east, and it's just a big cloud going from the coast all the way to the Channel Islands," he said of smoke from the fire.

"The sun is just rising, but it looks a little bit like sunset because the cloud is covering the sun," he said.

Wildfires also were burning in Arizona near the Mexican border.

One blaze covered about 4,000 acres near the city of Sierra Vista. It had destroyed three homes and sent an area resident to the hospital with third-degree burns, according to the National Forest Service.

Three other smaller fires in the area were largely or completely contained, fire officials said.
