The murder of Trayvon Martin

Trayvon Martin, 17 (above), was shot to death on February 26 while walking to his dad's girlfriend's house from a convenience store just north of Orlando, Florida. He was unarmed, wearing a hoodie, and carrying some Skittles and iced tea he purchased at the mini-mart.

George Zimmerman, 28 (inset), is the neighborhood watch volunteer who shot Trayvon. Zimmerman told police he shot the young man in self-defense. As more information about the incident emerges, this explanation sounds increasingly less plausible.

The case has sparked widespread interest and outrage online, in part because Zimmerman remains free, and Trayvon was an innocent kid doing nothing wrong, who cried out for help as he was attacked. His only threat, it seems, was being a black male.

A roundup of links for further reading and following, as the case evolves:

• "How we can leverage the anger over individual incidents into a larger restructuring of perceptions and justice," asks journalist Farai Chideya. "It's easy to work up ire about individual cases, but harder to work on systemic change." She's on Twitter here.
Charles Blow at the New York Times has been on the story. One item is here, but his Twitter feed is well worth a follow for ongoing (and paywall-free) updates.
Ta-Nehisi Coates, senior editor for The Atlantic, has been reporting on the case as well. He's updating on Twitter, too.
• The blog for MSNBC's Melissa Harris-Perry show is a good source of updates, and the show itself has been covering the case as well.
Think Progress has a "what everyone should know" post here.
• Zimmerman has been variously identified as "White," and "White Hispanic." An NPR opinion piece asks, What if he were black?
• At the Huffington Post, Trymaine Lee has been on the story for weeks, with strong reporting. Worth a Twitter follow.
