Chicago — 22-year-old Tylesha Griffin has been arrested and accused with first-degree murder for allegedly beating her 3 year old son to death with a belt and electrical cord.

Griffin, who was pregnant with her second child at the time, left the house earlier in the day, leaving the toddler in the care of a relative.

The child was found by police hours later, surrounded by vomit and covered by burn marks. He was rushed to the hospital but died just an hour later. Police became suspicious of Griffin when they found out that instead of taking her child to the hospital, she had cleaned the child up and tucked him back into bed as if nothing had happened.The boy was struck over 100 times all over his body. The death has been classified as

a homicide due to the “abusive injuries” the boy endured.
