A photograph published by ABC News this morning shows what the network says is the head of George Zimmerman covered in blood. ABC News says the picture was taken minutes after Zimmerman shot Trayvon Martin to death.

The 28-year-old neighborhood watch volunteer is charged with second-degree murder in the shooting, but he has maintained that he shot Martin, who was unarmed and on his way back from buying candy and tea, in self defense.

I'm Michel Martin and this is TELL ME MORE from NPR News. Coming up, we are going to go to Sweden, where a cake and a minister who seemed to have too much fun cutting it have sparked international protests. We'll tell you more about this in just a few minutes.

But first, it's time for Faith Matters. That's the part of the program where we talk about matters of faith and spirituality. Catholic parishioners in the Cleveland area were thrilled this week when Bishop Richard Lennon announced he will reopen 12 churches.

MICHEL MARTIN, HOST:

I'm Michel Martin and this is TELL ME MORE from NPR News. Earth Day is Sunday and in anticipation of that we're going to spend some time revisiting one of the worst environmental disasters in our nation's history: the BP oil spill. It's been exactly two years since the Deepwater Horizon rig exploded some 50 miles off the Louisiana coast.

UPDATE at 11:10 a.m. EST:

Judge Kenneth Lester says George Zimmerman can go free as he awaits trial if he posts a $150,000 bail.

Lester said as a condition of his release, Zimmerman would be electronically monitored, could have no contact with Trayvon Martin's family and would be prohibited from possessing firearms or using alcohol. He will also be on a curfew and have to check in every three days.

The judge said once he is assured that security measures have been met, Zimmerman will be freed.

UPDATE at 11:50 a.m. EST:

The Associated Press quotes Defense Minister Chaudhry Ahmed Mukhar as saying the 737-200 went down in a farm field of a relatively unpopulated area just a few miles from the international airport in Islamabad.

Mukhar said it was unlikely that anyone had survived.

Pakistani television showed wreckage of the plane, including parts that appeared to be the engine and the wing up against a small building, AP says.

UPDATE at 11:00 a.m. EST:

Levon Helm, the longtime drummer of The Band who backed Bob Dylan and sang with Van Morrison, died Thursday after a lengthy battle with cancer. He was 71.

When you think of the Hanford Nuclear Reservation, its radioactive legacy usually comes to mind. But, as correspondent Courtney Flatt reports, there’s more to clean up than just the site’s nuclear waste.

The Department of Energy wants to cut back commuter traffic at the nation’s most contaminated nuclear site.

Nearly 10,000 workers travel to and from Hanford on a daily basis. That’s a lot of traffic, and most of those cars hold just one person.

Arithmetic can be quite enlightening sometimes. One of the country's top agricultural economists just fiddled with the government's balance sheet on crop insurance, and arrived at a shocking conclusion: We'd spend billions of dollars less than we do now if we just gave away a simplified version of the insurance for free.
