LOOK: 10-year-old arrested in 2-year-old cousin's death

Detectives have arrested a 10-year-old in connection with the death of his 2-year-old cousin in Marion County.

.Berhaun Blyden was charged with aggravated manslaughter of a child in the death of 2-year-old Journee Bly.

Detectives were originally told Journee fell from her playpen. After an investigation, detectives determined the 10-year-old caused the fatal injuries, according to MCSO.

Another child, who is considered a witness, told detectives the 10-year-old had physically abused her and Journee when the three were unsupervised.

When detectives went to the 10-year-old with this information, he told them he was running while holding Journee and fell on the kitchen floor, causing her injuries.

The 10-year-old said he put Journee on the counter and "accidentally" pushed her off the countertop, detectives said

The Medical Examiner concluded Journee's injuries would have taken excessive force to create and ruled the child's death a homicide.
