Using the notion of a final act mentality, we operationalize suicidality as not only intentionally ending one\u2019s life but also as accepting that committing the act will end one\u2019s life as they know it. To assess the rate of suicidality in public mass shooters, we analyze publicly available data on plans to avoid capture, initial outcomes post-attack, and suicidal capability for 54 offenders who killed six or more people between January 1, 2000, and May 6, 2023. Our findings indicate that nearly all public mass shooters were suicidal at the time of the attack. Although based on a small sample, we found no statistically significant difference in suicidal capability between those who lived versus those who died by suicide.\n                  <\/jats:p>","DOI":"10.1177\/00302228261492870","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T10:04:55Z","timestamp":1790417095000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Public Mass Shooters and the Prevalence of Suicidality"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4163-9009","authenticated-orcid":false,"given":"Peyton","family":"Henry","sequence":"first","affiliation":[{"name":"Department of Applied Social Sciences, Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5685-7933","authenticated-orcid":false,"given":"Mina","family":"Velimirovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"},{"name":"University of Novi Sad"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anika N.","family":"Sigel","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie T.","family":"Campione","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie R.","family":"Abber","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"},{"name":"Department of Psychiatry, University of California, San Diego"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanaika","family":"Shetty","sequence":"additional","affiliation":[{"name":"Department of Applied Social Sciences, Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8685-9259","authenticated-orcid":false,"given":"Morgan","family":"Robison","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esther C.","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Joiner","sequence":"additional","affiliation":[{"name":"Department of Psychology, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9577-2817","authenticated-orcid":false,"given":"James","family":"Silver","sequence":"additional","affiliation":[{"name":"Department of Applied Social Sciences, Boston University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,26]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/01639625.2018.1437653"},{"key":"e_1_3_4_3_1","volume-title":"What we know about the highland park shooting suspect","author":"Andone D.","year":"2022","unstructured":"Andone D., Almasy S., Devine C.
