The man charged in the death of his 2-year-old cousin pleaded not guilty by reason of insanity in February.

Roman Morales, 21, was ordered to undergo an evaluation at the Colorado Mental Health Institute.

His case will be reviewed May 20th.

Lakewood Police found the little boy unresponsive in a Lakewood apartment Sept. 21. Police said a cord was wrapped around his neck.

Morales was charged with two counts of first-degree murder and child abuse.

Morales was arrested Sept. 22 after Lakewood Police said they received a call saying the boy had been missing shortly before noon Sept. 21.
