Democratic Gov. Andrew Cuomo plans to visit a hospital where a New York correction officer is recovering from injuries suffered when he opened a package that exploded at his home.

The governor's office says he'll be at Upstate University Hospital in Syracuse on Monday afternoon after marching in a Memorial Day parade on Long Island.

Authorities say the 52-year-old correction officer suffered serious burns to his hands and arms Sunday morning when he opened a package near his mailbox in the Oneida County town of Lloyd, about 35 miles east of Syracuse.

Agencies are still trying to determine whether the blast was related to the victim's work.

Sheriff Robert Maciol (MAY'-shuhl) says Monday that investigators spend 12 hours processing evidence at the scene. He says no arrests have been made.
