NORTON SHORES, Mich. (AP) — Authorities say a West Michigan man has been charged in the death of his 2-month-old son.

Forty-year-old Anthony Casanova was arraigned Monday on one count of open murder in 60th District Court. The Muskegon Chronicle reports (http://bit.ly/XePsu9 ) that Magistrate Michael VanEpps denied bond.

Police searched a home near Muskegon on Friday and arrested Casanova. Prosecutors say an autopsy Saturday found that the boy had significant injuries.

The Associated Press left a message Monday afternoon for Casanova's attorney Perry Nolan.
