The lawyer for a New Jersey man whose 4-year-old son shot and killed a 6-year-old playmate says his client is cooperating.

Robert Ebberup released a statement Wednesday in which he criticized the Atlantic County Prosecutor's Office for arresting his client in front of his family while they ate dinner.

The lawyer says Anthony Senatore would have voluntarily turned himself in to face charges of child endangerment and enabling access by a minor to a loaded firearm.

Authorities say Senatore's son took a loaded .22-caliber rifle from a bedroom on April 8 and fatally wounded neighbor Brandon Holt while they were playing outdoors.

Officials say four shotguns were found close to ammunition and accessible to Senatore's three children in their Toms River home.

He's due in court Thursday.
