A Fingerville woman received a 30-year prison sentence today after she admitted to feeding her daughter a lethal dose of salt.

Kimberly N. Martines, 25, pleaded guilty to homicide by child abuse. Martines poisoned her 17-month-old baby girl, Peyton Martines.  The victim was unresponsive when Spartanburg County Emergency Medical Services responded to the family home about 5:15 a.m. on July 31, 2016. Peyton was severely dehydrated and she appeared to be having a seizure. When the baby arrived at the Spartanburg Medical Center Emergency Room, she had a temperature of 103.2 degrees and an inflated amount of sodium in her blood. The baby died three days later in the hospital’s pediatric intensive care unit. The autopsy revealed a clinical brain death secondary to a high concentration of sodium.

“The overdose of salt caused Peyton’s brain to shut down,” Assistant Solicitor Jennifer Jordan said. “It was a senseless tragedy that was caused by someone who made a horrible choice.”

Kimberly Martines initially reported that Peyton and her twin sister got into a bag of salt that was left on a book case the night before. Kimberly Martines reported the twins covered themselves in salt but she bathed them and placed the babies in bed. Investigators with the Special Victims Unit of the Sheriff’s Office learned that Kimberly Martines wasn’t telling the truth after they interviewed Kimberly Martines’ 4-year-old son. The little boy reported that he watched his mother feed his sister a full spoon of salt. The boy described the spoon and the bag of salt in detail. The information helped deputies find the bag of salt under a sofa cushion.

Kimberly Martines changed her story once deputies confronted her with the new information. She admitted to feeding Peyton a tablespoon of salt in an attempt to get her estranged husband to come home. When asked why she picked Peyton, she said she picked the child who was closest in proximity to her at the time. 

Kimberly Martines will serve 85 percent of Circuit Judge Mark Hayes’ prison sentence before she is eligible for release.
