1. True Crime New England's Case Profiles #88 presents two Connecticut homicide cases involving people of color who received limited media attention. 2. Liz Corey and Katie King host the episode, with Liz presenting Tyshawn Hargrove's case and Katie presenting Olga Maria Cornelis-Ubiera's case. 3. The episode asks what can be documented about unsolved New England cases when media coverage, law-enforcement attention, and available records are limited. 4. Tyshawn Hargrove was born on September 11, 2006, and grew up in New Haven with two brothers and two sisters. 5. Tyshawn's coach Robert McIver described changes in his life after COVID-19, while Tyshawn continued to value basketball, Xbox, Bible study, and church. 6. Fair Haven police responded to multiple gunshots on Chatham Street at 10:51 p.m. on August 28, 2021. 7. Officers found 14-year-old Tyshawn with multiple gunshot wounds, and he was pronounced dead at Yale New Haven Hospital. 8. Tyshawn was weeks from turning 15, preparing to enter Hill House High School, and had a one-year-old son named Aiden. 9. The hosts say surveillance footage and neighborhood canvassing produced no immediate leads, although people were present around Tyshawn when police arrived. 10. Dashauna's Youth Without Limits organization created Tys' Hoop Dreams in March 2022 as a basketball, mentoring, and safe-space program for Connecticut children. 11. Tyshawn was identified as New Haven's 19th homicide victim in 2021, and the hosts cite gun assault as the leading cause of death for New Haven men ages 15 to 39. 12. Olga Maria Cornelis-Ubiera was 32, came from the Dominican Republic, and lived with family in Bridgeport, Connecticut. 13. Olga was last confirmed alive on October 29, 1994, after friends declined another request to drive her across town to visit her boyfriend. 14. Men driving to work found Olga's body near Route 262, also called Waterbury Road, on November 1 at approximately 10:45 a.m. 15. Investigators found Olga unclothed and badly beaten, with multiple blunt-trauma injuries, stab wounds, and clothing that was never recovered. 16. A black beeper with its clip broken off was found near Olga and led police to her address through its connection to Michael Knox. 17. Olga's case was considered alongside the unsolved killings of Karen Everett and Mildred Alvarado near Harwinton, although investigators noted differences involving sex work, substance use, and the methods of death. 18. The episode uses a conversational two-case format, with Liz and Katie reacting to the evidence, unanswered questions, and the lack of public information. 19. Listeners seeking unsolved Connecticut homicide case profiles. 20. Listeners wanting resolved cases or lighter subject matter.
