Deputy's son arrested in killing of mother, sisters

LAWRENCEVILLE - A 17-year-old who faces murder charges in the shooting deaths of his mother, a Gwinnett County sheriff's deputy, and two younger sisters waived his initial court appearance Friday.

Anthony Tyrone Terrell Jr. is being held without bond in the DeKalb County Jail. He was taken to a neighboring county to avoid potential conflicts because his mother was an employee of the Gwinnett County Sheriff's Department.

Gwinnett County police on Thursday evening found the bodies of Deputy Joy Deleston, 39, and her two daughters, Micaiah, 11, and Jelani, 4, inside of their home southeast of Lawrenceville.

Terrell was not at the Madison Chase Drive home when police arrived. Officers interviewed him that evening and found probable cause to charge him with three counts each of murder and aggravated assault.

Police said the motive of the crime is still under investigation.

Gwinnett County Public Schools spokeswoman Sloan Roach said records show Terrell is enrolled as a sophomore at Central Gwinnett High School in Lawrenceville. Roach said Micaiah was in sixth grade at Richards Middle School.

Deleston worked for the Sheriff's Department for seven years, and she was most recently assigned to the Sex Offender Unit.
