  "context": "Riley Strain was a 22-year-old [University of Missouri senior](https://www.today.com/news/news/missing-missouri-student-riley-strain-rcna143239) and Delta Chi fraternity member from Springfield, Missouri. On Friday, March 8, 2024, he was on a fraternity spring formal trip in Nashville, Tennessee. Around 9:30 PM CST, he was [asked to leave Luke Bryan's downtown bar Luke's 32 Bridge](https://www.cbsnews.com/news/riley-strain-missing-student-nashville-body-found-search/), and surveillance video showed him stumbling along Gay Street and toward the Cumberland River area. The University of Missouri was [alerted by his fraternity and family on March 11, 2024](https://showme.missouri.edu/2024/mu-officials-provide-support-counseling-in-search-for-missing-student/), and MU President Mun Choi's office issued a campus-wide notification under the [Higher Education Opportunity Act of 2008](https://en.wikipedia.org/wiki/Higher_Education_Opportunity_Act) framework. The Metropolitan Nashville Police Department led the multi-week investigation, with assistance from the United Cajun Navy and over 200 public tips. On March 22, 2024, [Strain's body was recovered from the Cumberland River near 61st Avenue in West Nashville](https://www.cbsnews.com/news/riley-strain-missing-student-nashville-body-found-search/), about 8 miles from downtown. The autopsy determined the cause of death was [drowning and ethanol intoxication](https://www.wbir.com/article/news/regional/riley-strain-autopsy-report/51-0484dfe5-574d-4c71-97c4-883df2cd298e); his blood alcohol content was 0.228, nearly three times the legal limit. The manner of death was ruled accidental. The case is significant in HEOA archive history because it required MU to issue a missing-student notification for a student who was 350+ miles from campus on a fraternity-sponsored trip, raising long-standing questions about institutional responsibility for off-campus organizational events. The Strain family later [filed a wrongful-death lawsuit against Delta Chi](https://www.komu.com/news/midmissourinews/family-of-riley-strain-files-wrongful-death-lawsuit-against-fraternity/article_bcfd6155-f6c9-4948-81e8-2ae2c8edaf71.html).",
  "keyFindings": [
    "MU's HEOA missing-student notification was issued for a student 350+ miles from campus on a fraternity-organized trip, testing the geographic limits of institutional missing-student responsibility",
    "MU President Mun Choi's 'Mourning a Tiger' message format pairs HEOA follow-up with counseling resources and is a recurring genre in MU's institutional voice",
    "The Strain family's subsequent wrongful-death lawsuit against Delta Chi raised broader questions about institutional and Greek-organization responsibility for student safety at off-campus events",
    "The 14-day search arc with 200+ public tips illustrates how high-profile HEOA notifications can mobilize regional and national attention well beyond the host university's geography"
