Tate Thurman, 4 February 18, 2020, East Peoria, Tazewell County, Illinois

Updated: Mar 15, 2022

Tate Thurman

Born December 3, 2015

Deceased February 18, 2020

A 911 call came in about a “slip and fall” at 109 Jefferson Court in East Peoria. First responders reported that four year old Tate Thurman was covered in bruises “head to toe” and police were called to the residence. Tate was in full cardiac arrest. Tate was brain dead at the hospital and died two days later. Baby Tate was in the hands of his father’s girlfriend Lesli Jett, when he lost his life.

Coming forth now is the history of DCFS involvement which began with a report investigating his mother in 2011 who later died in 2017. The children that were removed then, returned to the home to live with their father in 2018. Since then, DCFS had no further involvement nor were they required to check on these children.

The father’s girlfriend Lesli has now been charged with three counts of First Degree Murder and an aggravated battery to a child. She was the only adult in the residence at the time. She’s being held on a $3 Million Bond (10% applies).

The coroner reported that Tate suffered blunt force trauma and tears to his intestines and bruises from head to toe. He also said that the story the suspect told was inconsistent with what he found. What Coroner Jamie Harwood found consistent, was abuse.

The coroner report includes that "Deep muscular bruising of the abdominal wall and back, an acute fracture of [Thurman's] right collarbone, and extensive contusions and abrasions to [his] scalp, face, neck, chest, [genital area], buttocks, upper back, shoulder, and limbs, including deep muscular bruising of the scalp, neck, torso."

25 News also reported court documents showing that the baby “had serious abdominal injuries including a large tear in his intestines and a pancreatic hematoma, causing internal bleeding. Doctors concluded that those types of injuries were caused by ‘high-velocity blunt force abdominal trauma.”

At OSF Saint Francis Medical Center, doctors also found extensive bruising and lacerations on multiple parts of Thurman's body, including a fractured clavicle. The document says doctors questioned Thurman's father and Jett after finding these injuries, but both repeated the explanation that the boy slipped on some water and became unresponsive.’

The other children in the home have since been removed from the home again.
