Summary

In the Central Criminal Court, the jury heard that Derek Boyd, who was on a suspended sentence for a prior shooting, allegedly stabbed Mark Carroll to death on 9 June 2024. Boyd's partner, Chantelle Harcourt, is accused of trying to clean the scene before Gardaí arrived. Witness Megan Rock testified that she, Mark, Boyd and another person drank cocaine in Boyd's garden on 8 June, left after Boyd told them to leave, and later returned to the house to see if they could stay the night. Rock said she saw Mark running out of the house with blood on his chest. She also claimed Boyd had pulled her by the hair and threatened her. Boyd and Harcourt have both pleaded not guilty to the charges. The trial will continue tomorrow before Justice Melanie Greally and a jury.
