The suspects, wanted for a 2 p.m. PDT lawnmower theft on the 100 block of North Verdugo Avenue in Glendora, were tracked by a Pasadena Police helicopter onto the campus. One suspect was detained at PCC; the lockdown at PCC was lifted at about 5:10 p.m. PDT and at Caltech at about 5:38 p.m. PDT.",
    "outcome": "One grand-theft suspect was apprehended after fleeing into a PCC parking structure on the Colorado campus. No injuries occurred at PCC or Caltech. PCC's lockdown was lifted at approximately 5:10 p.m. PDT; Caltech's lockdown was lifted later, at approximately 5:38 p.m. PDT. The original Glendora theft — described in early reports as a 'robbery' but later clarified as grand theft of a lawnmower — was a relatively minor property crime that nonetheless triggered a multi-mile pursuit and dual-campus lockdown. Initial police reports described the suspects as 'armed,' but later updates indicated they were not.",

  "context": "[Pasadena City College](https://pasadena.edu/) is one of the largest community colleges in Los Angeles County, with its main campus on Colorado Boulevard adjacent to the [California Institute of Technology](https://www.caltech.edu/). On the afternoon of [Thursday, July 7, 2022](https://abc7.com/pasadena-city-college-school-lockdown-california-institute-of-technology-caltech/12028974/), Glendora Police responded to a [grand theft of a lawnmower](https://pasadenanow.com/main/search-for-robbery-suspects-prompts-hours-long-lockdowns-at-pasadena-city-college-caltech) at approximately 2 p.m. PDT on the 100 block of North Verdugo Avenue in Glendora. Three suspects fled toward Pasadena and were eventually tracked by a Pasadena Police helicopter into a parking structure on PCC's Colorado campus. At approximately 3:45 p.m. PDT, PCC tweeted a campus-wide shelter-in-place. [Caltech](https://www.cbsnews.com/losangeles/news/pasadena-city-college-in-lockdown-due-to-police-activity/) (across Colorado Boulevard) issued its own lockdown shortly after, a notable cascade given Caltech's status as a private R1 university and PCC's as a community college sharing only geographic proximity rather than any institutional affiliation. PCC's lockdown lasted approximately 85 minutes; Caltech's lasted longer. One suspect was [apprehended in the parking structure](https://ktla.com/news/local-news/caltech-pcc-on-lockdown-amid-robbery-investigation/), and PCC issued an all-clear at approximately 5:10 p.m. PDT, while Caltech did not lift its own lockdown until approximately 5:38 p.m. PDT. The case is significant for the campus alert archive because it documents a community-college and R1-private cross-institution cascade lockdown driven purely by geographic proximity, analogous in form to the Atlanta University Center cascades but with the unusual feature that the two cascading institutions share no organizational, athletic, or academic relationship.",
  "keyFindings": [
    "PCC and Caltech (institutions with no organizational relationship) issued separate lockdowns within minutes of each other based purely on geographic proximity across Colorado Boulevard",
    "The underlying trigger was a relatively minor property crime (grand theft of a lawnmower) in Glendora that escalated through a multi-mile pursuit",
    "PCC's lockdown lasted approximately 85 minutes (3:45 p.m. PDT to 5:10 p.m. PDT); Caltech's lockdown was lifted later, at approximately 5:38 p.m. PDT, showing that adjacent campuses do not always coordinate identical timing",
    "One of three grand-theft suspects was apprehended after fleeing into a PCC parking structure, illustrating how community-college open campuses can become escape routes from urban pursuits",
    "Pasadena Police air support and ground units coordinated with both campus security operations during the search"
