Nurse and Boyfriend Arrested after 4-Year-Old with Herpes, Dies

HOUSTON - A 4-year old whose body was covered in injuries is dead.

Child protective services first learned of Emma Thompson last month after the 4-year old was diagnosed with a sexually transmitted disease.

Blisters in the little girl’s mouth, hands and genitals turned out to be herpes simplex two.

Less than 3 weeks later, the little girl was dead with extensive injuries. She had a skull fracture, internal bleeding, lacerated pancreas and there was evidence she was sexually assaulted.

CPS says it did not take custody of the 4-year-old because genital herpes can also be spread through non-sexual contact and an early examination of the little girl did not reveal physical evidence of sexual abuse.

The girl's mother, Abigail Young, is a registered nurse.

Estella Olguin with CPS says Young initially told CPS no man had access to her three daughters. Young is going through a divorce and lives separate from her husband.

Olguin says CPS has since learned the little girl's mother's boyfriend Lucas Coe was living with the family. Coe has a long history with CPS and was previously charged with injury to a child. Coe lost custody of his children a few years back.

No one has been charged in the 4-year-old's death. CPS now has custody of Young's two older daughters, ages 6 and 11.
