2. Search Intensifies for Shooting Spree Suspect in Pennsylvania

A suspect in a deadly shooting rampage remains on the run outside of Philadelphia this morning, forcing residents to stay indoors and local schools to close as a precaution.

Bradley William Stone, 35, is suspected of killing six members of his ex-wife’s family at three separate locations in Montgomery County – allegedly killing his ex-wife, his former mother-in-law, former grandmother-in-law, sister-in-law, brother-in-law and 14-year-old niece.

His former nephew, 17, was wounded and taken to a hospital in Philadelphia for treatment. Stone took his two children to a neighbor's home before the shootings began, Montgomery County District Attorney Risa Vetri told reporters, and they are safe.

3. Attacker in Sydney Siege was 'Deeply Disturbed,' Australia PM Tony Abbott Says

Australia Prime Minister Tony Abbott said the hostage taker in Monday’s siege in Sydney was a “deeply disturbed individual” who was drawn to extremist views during a life marked by mental instability and crime.

Abbott, speaking at a press conference with other authorities today, said he believes that no one would want to emulate the actions of Man Monis, who took control of a chocolate shop in downtown Sydney, leading to a 16-hour standoff. Monis and two others were killed during the siege.

“The tragedy of these times is that there are people even in a society such as ours who wish to do us harm. We are not immune to the politically motivated violence which has for so long stalked other countries,” Abbott said.

“There was nothing consistent about this individual’s life, except that he was consistently weird.”

4. Bill Cosby's Wife Camille Defends Him as 'Kind, Generous, Funny'

Bill Cosby's wife, Camille, spoke out in support of her husband, and suggested that the media has been quick to report unvetted accusations against him.

Camille Cosby said in a statement that her husband has been unfairly victimized by the allegations of sexual misconduct that have been leveled against him recently. Bill, she said, is the man that the public has long known through his work. "A different man has been portrayed in the media over the last two months. It is the portrait of a man I do not know. It is also a portrait painted by individuals and organizations whom many in the media have given a pass," she said.

"The man I met, and fell in love with, and whom I continue to love, is the man you all knew through his work. He is a kind man, a generous man, a funny man, and a wonderful husband, father and friend," she added. "He is the man you thought you knew."

5. More Teens Using E-Cigarettes Than Tobacco Cigarettes, Survey Finds

For the first time, more teens are smoking e-cigarettes than tobacco cigarettes, according to a new survey of 40,000 to 50,000 students in the 8th, 10th and 12th grades.

The annual University of Michigan "Monitoring the Future" report found that both alcohol and cigarette use in 2014 were at their lowest points since the study began in 1975. But they were most concerned about the rise of e-cigarettes, which are not regulated and whose formulas are undisclosed.

"As one of the newest smoking-type products in recent years, e-cigarettes have made rapid inroads into the lives of American adolescents," Richard Miech, a senior investigator of the study, said in a statement. "Part of the reason for the popularity of e-cigarettes is the perception among teens that they do not harm health."
