Authorities in New Orleans say a body believed to be New England Patriots player Marquise Hill was found by searchers yesterday — one day after he was reported missing in a jet ski accident. The body turned up about a quarter-mile from where Hill and a female companion were involved in the accident on Lake Pontchartrain. The woman Hill was with survived and was rescued from the river. Hill was 24 years old. He was a defensive end with the Patriots and had spent much of his time since Hurricane Katrina helping family members rebuild their homes.
