LAS VEGAS » A 23-year-old Las Vegas father told police he knelt on his 7-month-old son’s chest before the boy died last week because he was angry the boy was being "fussy" even after being fed.

Cornelio Rodriguez-Gonzalez was being held Monday at the Clark County jail pending a court appearance on a murder by child abuse charge in the death of his son, Raymond.

The 255-pound Rodriguez-Gonzalez was arrested Nov. 18 after initially telling the boy’s mother, Amy Elliott, that the child had fallen while she was at work.

A police report says authorities found bruises on the child’s face and hip, scrapes on the back of his head, partially healed rib injuries and a lacerated liver was that was believed to have led to his death.
