"The Brevard County Sheriff's Office had a duty not to retain deputies like Santiago-Miranda, who has repeatedly shown that they were unfit for service, and expose citizens" like Crooms and Pierce "to such unfitness," the lawsuit alleges. "The Brevard County Sheriff's Office breached that duty when it retained and placed Santiago-Miranda armed on the street of Brevard County, despite his criminal history and demonstrated violent tendencies over the course of more than a decade. and as recently as a few months before killing A.J. Crooms and Sincere Pierce." The lawsuit alleges that Santiago-Miranda "had an alarming and disqualifying criminal history" of such a level that he should not have been a deputy.
