A visitation is being held for a firefighter who was fatally shot while responding to a call for help at a home in a Maryland suburb of Washington.

A visitation for firefighter John Ulmschneider is being held Tuesday evening at St. John's Catholic Parish in Hollywood, Maryland. A funeral is being held at the same place at 1 p.m. Wednesday with a private family burial to follow.

Ulmschneider was killed Friday when firefighters went to a Temple Hills home after the brother of the man who lived there told authorities he was concerned about the man. When the firefighters arrived, the person inside was unresponsive, so they decided to force entry. As that was happening, the person inside fired several rounds.

An investigation is ongoing. No one has been charged.
