The standoff between a murder suspect and French police in Toulouse, France, has stirred up a swirl of speculation about the man's background and motives, but so far there are relatively few confirmed facts.

French officials say the suspect is a 23- or 24-year-old Frenchman of Algerian decent by the name of Mohammed Merah, who had a long record as a juvenile delinquent.

He's suspected in the killings this month of three French paratroopers of North African descent, as well as a rabbi and three Jewish schoolchildren.

Saying that Mitt Romney may not be able to "grind his way toward the nomination" despite a huge fundraising advantage, former House Speaker Newt Gingrich told NPR today that he sees no reason to exit the Republican presidential race and that there's a chance of a new contender emerging at the party's convention in August.

"I'm not so sure you wouldn't get a series of brand new players" stepping forward during a brokered convention, he told Morning Edition co-host Steve Inskeep.

Nika Roza Danilova, known on stage as Zola Jesus, has crafted an experimental, genre-straddling sound which incorporates Gothic rock, lo-fi acoustic music, orchestral instrumentals, ambient electronic sounds and strong, diva-esque vocals. She's released three full-length studio albums in the span of three years, and each has sounded more purposeful and powerful than the last.

The Denver Broncos have traded quarterback Tim Tebow to the New York Jets in exchange for a fourth-round and a sixth-round draft pick, Newsday is reporting.

Tebow became redundant in Denver after the team signed Peyton Manning to a five-year, $96 million contract. Newsday adds:

New Orleans Saints head coach Sean Payton has been "suspended for one season without pay for his involvement in the team's bounty program," NFL.com reports.

The team's former defensive coordinator, Gregg Williams, "has been suspended indefinitely." He ran the program that paid players bounties for hits that knocked opponents out of games. Williams left the Saints after last season to join the St. Louis Rams.
