San Luis Obispo County saw major developments Tuesday across crime, transportation and local government. From new evidence in the Kristin Smart case to a $51 million public safety complex, here’s a roundup of the day’s top stories.

Here are key takeaways:

  • Kristin Smart case update: Scientists found “very strong” evidence of decomposing human remains compounds in soil samples from a walkway on Susan Flores’ Arroyo Grande property, scientists say, though the Sheriff’s Office ended its search Saturday without recovering Kristin Smart’s body.

  • CHP identifies man killed in crash: Matthew Baumgardner, 48, of Paso Robles was killed when a Chevrolet Camaro veered off Nacimiento Lake Drive and struck a tree Sunday night. Driver Joseph Mitchell Pate, 44, was arrested on suspicion of DUI and sustained major injuries, while front passenger Mack Garcia suffered minor injuries.
  • Big-rig crash on Highway 101: A portion of Highway 101 in Pismo Beach was closed overnight after a semi-truck hit the large arm of a piece of Granite Construction machinery around 10 p.m. The crash had diesel fuel pooling in portions of the road and forced an extended closure of the highway into Tuesday morning.
  • Kid riding e-bike injured in collision: A 12-year-old riding an e-bike without a helmet was critically injured Saturday afternoon after colliding with a car near DeVaul Park in San Luis Obispo. The child has undergone multiple surgeries and was in stable condition at an out-of-area trauma center as of Tuesday.
  • Local food truck carries on family legacy: Brittany Gonyer’s Wandering Eats food truck continues the legacy of The Crushed Grape, her mother’s former SLO wine and gift shop. Gonyer bought a parrot green ice cream trailer at auction for $20,000 in 2018 and pivoted to wraps after fire regulations made her original quesadilla cone concept unworkable.
  • Highway 101 construction: Drivers will encounter overnight lane closures on Highway 101 between Pismo Beach and Arroyo Grande nightly from 7 p.m. to 7 a.m. through May 15. Caltrans says one lane in both directions will remain open during the pavement rehabilitation and drainage project.
  • New fire and police station: Pismo Beach cut the ribbon Monday on its new $51 million Public Safety Center combining police and fire services on Bello Street. The Fire Department’s new 14,000-square-foot station is expected to reduce response times by two to three minutes by housing personnel and vehicles together.
  • Building height vote may happen in Grover Beach: A citizen-led initiative to limit building heights in Grover Beach collected 1,102 valid signatures, exceeding the 793 required for the November ballot. The City Council will decide June 8 whether to adopt the measure as an ordinance or send it to voters.
