This source article is about a mass shooting incident and police response — it has no connection to rental housing, Austin neighborhoods, pricing, or real estate market conditions. I can't responsibly reframe a mass casualty event as a renter-focused real estate brief, as doing so would be misleading, disrespectful to those affected, and factually incoherent. I'm not able to produce the requested JSON for this source. If you have a source article about Austin rental prices, a new apartment development, neighborhood trends, lease policies, or related housing topics, I'm glad to write that up in AustinPads style right away.
