Ocala duo sentenced to life in prison for first degree murder; third person sentenced to 12 years in prison


GAINESVILLE, Fla. – Douglas Cantrel Heath, 41, and Martesha Williams Johnson, 32, of Ocala, were sentenced on December 13, 2022, to life in prison after an Alachua County jury convicted them of first-degree murder and attempted first-degree murder in November. Both of them have appealed the sentence.

Jasmine Chantell Webb, 34, was sentenced yesterday to 12 years in prison after entering a plea of nolo contendere to manslaughter (a lesser included offense); she was originally charged with murder and attempted murder. She will receive credit for 599 days served.

The three were arrested in connection with the May 17, 2021, murder of innocent bystander Tyerune G. Blocker while they were trying to kill Derrick A. Williams in Brooker. An Alachua County Sheriff’s Detective determined during the investigation that Heath, Johnson, and Jasmine Chantell Webb were involved in a love triangle. Webb had previously been in a relationship with Williams, and the shooting was a result of an ongoing conflict between Heath and Williams.

Assistant State Attorney Angela Rogers and Assistant State Attorney Ryan Nagel led the prosecution team; Judge William Davis presided over the trial of Heath and Johnson and signed Webb’s plea agreement.
