JACKSONVILLE, Fla. -- CPR Awareness Week is wrapping up with an emphasis on saving lives.

Most critical, instructors said there is more emphasis on chest compressions for beginners. It is best to focus on compressing the chest about 2 inches, instead of taking breaks for mouth-to-mouth, they said.

The Northeast Florida Safety Council has regularly scheduled CPR training classes.

Instructor Derrick Brinson has taught CPR for 18 years and said people should focus on those compressions to get the heart pumping again.

JACKSONVILLE, Fla. -- A 12-year-old boy indicted Thursday in the murder of his 2-year-old half brother may have been responsible for a broken leg the toddler sustained earlier this year.

Cristian Fernandez was indicted Thursday for hitting his half brother David Galarriago on the head at least twice on March 14, killing him, said State Attorney Angela Corey after a grand jury handed down the decision.

Fernandez is charged with murder in the first degree and aggravated child abuse. Biannela Marie Susana, Fernandez' mother, was also charged, with aggravated manslaughter of a child.

According to an arrest and booking report from the Jacksonville Sheriff's Office, on Jan. 22 David broke his leg. Initially, their mother said it was from a fall, but later admitted she had lied and that Fernandez broke his brother's leg while wrestling.

JACKSONVILLE, Fla. -- The Sharks rivalry with the Predators will soon hit a high point: five billboards across Orlando.

Back in April, the Sharks paid for a billboard in Jacksonville saying "Jacksonville sucks. See you rednecks April 30. Love the Orlando Predators."

"They don't like us and we don't like them," said Sharks owner Jeff Bouchy. "I thought it was kind of funny, but I know they didn't mean it to be funny."

The Sharks are returning the favor in preparation for next week's the matchup with Orlando.

Bouchy, watching the game at Whisky River Friday night, said they won't have just one message for Orlando.

"They're going to be the LED boards that can change," Bouchy said. "We can tell Orlando a lot of things in five days."

They will have thousands of messages on rotation and an (almost) live twitter feed.

The messages will be screened and reposted on five billboards around Orlando.
