Q: The exact number of exonerated American prisoners is unknown. But data gathered by university law schools indicates it's more than 2,000. Fascinating details surrounding some of these exonerations set them apart from the rest. Here are five recent exonerations that made headlines.

1. Michael Morton

The subject of a CNN film, Michael Morton wasn't home when his wife, Christine, was beaten to death in front of their 3-year-old son at their Austin, Texas-area home in 1986. But a prosecutor said the evidence suggested otherwise. The problem was, the jury was prevented from hearing all the evidence in the case.

Wrongly convicted of murder and sentenced to life in prison, a team of loyal supporters and DNA evidence helped Morton win his freedom in 2011. Last month, Morton's former prosecutor pleaded no contest to a court order to show cause regarding evidence that was not used in the trial.

2. Brian Banks and the incredible twist

At age 17, fearing a potentially long sentence, college football hopeful Brian Banks followed the advice of his attorney and pleaded no contest to assaulting a Long Beach, California, high school classmate in 2002.

Banks maintained his innocence throughout nearly six years of imprisonment, subsequent probation and registration as a sex offender.

But in 2011, the case took an incredible twist when the alleged victim sent Banks a Facebook friend request.

According to the California Innocence Project, the woman later admitted that Banks had not kidnapped or raped her during a consensual encounter at Long Beach Polytechnic High School, where Banks was a middle linebacker with a scholarship offer from the University of Southern California.

Q: (CNN) -- World number three Roger Federer exited the Monte Carlo Masters at the quarterfinals stage to Austrian Jurgen Melzer Friday.

Melzer was securing his first victory over the 16-time grand slam champion as he ran out a 6-4 6-4 winner at the prestigious clay court event.

It was the earliest defeat for Federer in a tournament this year, ending his hopes of claiming the Monte Carlo title for the first time after being beaten three times in the final by Rafael Nadal.

He has drawn blank since claiming the ATP season-opener in Doha, Qatar.

Federer had breezed to the last eight, but was always struggling against Melzer in blustery conditions.

Melzer broke for 3-2 in the opening set after an errant Federer forehand and held on to close it out.

The second followed a similar pattern, with Federer unable to capitalize on his seven break points in the match as the seventh seed went through.

Melzer was delighted to finally get past his old nemesis in such convincing fashion.

"He beat me three times last year and I didn't even win a set," he told AFP.

"But many things went well for me, my shots worked well. When he had break points I was calm and served well.

"I did well on the big points and played my game."

Federer shrugged off his defeat as he now takes a two-week break before the Madrid Masters in his build-up to the French Open next month.
