COLUMBUS, Ohio — An Ohio police officer whose cruiser slammed into a stopped car in the middle of an intersection tried to veer away but couldn't avoid the crash that killed six members of a family, and there is no basis to charge him, authorities announced Thursday.

Investigators concluded that the other driver entered a Columbus-area intersection despite a red light and was struck on the side by an Upper Arlington police cruiser that was responding to a middle-of-the-night robbery call with its lights and sirens activated. The Oct. 18 crash killed the driver, his wife and four of their daughters, and the police officer was seriously hurt.

“It was a dreadful accident, and given the actions of the other driver, it was unavoidable,” Perry Township police Chief Robert Oppenheimer said in a statement Thursday.

There were no signs that the driver, Eid Badi Shahad, was impaired. Exactly why he ran the red light or stopped in the intersection is likely to remain a mystery.

ATLANTA — Flu season seems to be winding down, and it’s been an odd one.It hasn’t been as bad as last year and the vaccine worked a little better. And it has been a fairly mild one for the elderly — traditionally the most vulnerable group. But it’s been a different story for young and middle-age adults, who have been hit harder than expected because of a surge in swine flu.Most flu seasons, only one-third of the people who land in the hospital with the flu are adults ages 18-64. This winter, they have accounted for two-thirds, most of them adults who were obese or had another ailment.The numbers “are painful reminders that flu can be serious for anyone, not just infants and the very old,” said Dr. Tom Frieden, director of the Centers for Disease Control.
