• The shooting was the second of three murders in a trail of carnage early Tuesday that spanned 25 miles -- but lasted just an hour. The shooter, 20-year-old Ali Syed, killed a woman in the home he shared with his parents, killed two drivers during carjackings, injured two others and shot up cars on a busy freeway interchange before committing suicide as police closed in, authorities said.
• Syed, an unemployed part-time community college student, had no known motive and acted alone, said Tustin police Chief Scott Jordan. The first victim, a woman in her twenties, has not been identified and was not related to Syed, he said.
• The violence began at 4:45 a.m., when deputies responded to a call from Ladera Ranch, a sleepy inland town about 55 miles southeast of Los Angeles. They found the woman shot multiple times.

• WASHINGTON (AP) -- President Barack Obama is talking about climate change like it was 2009.
• The president, who rarely uttered the words "climate change" or "global warming" during the second half of his first term and during the re-election campaign, has re-inserted it boldly back into his lexicon. In his latest State of the Union address before Congress, Obama sounded like he did in his first, urging lawmakers to limit gases blamed for global warming "for the sake of our children and our future." Those words followed his inaugural address, in which he said, "We will respond to the threat of climate change."
• The difference between then and now is that Obama knows Congress is unlikely to agree. He said that if Congress won't act, he will through executive action. The question is: What will he do?
• In his toolbox are things as small as requiring appliances to be more efficient and as big as controlling the largest single source of heat-trapping emissions: the carbon pollution from the nation's coal-fired power plants. How boldly will he act in the face of inevitable pushback from industries and the costs of any new regulations to the fragile economy?
• Environmentalists already are pressing Obama to kill the proposed Keystone XL oil pipeline from western Canada to refineries on the Texas Gulf Coast as a first public test of his commitment to climate change.
