(AP & WHAM News)_ The brother of a 19-year-old volunteer firefighter slain during a Christmas Eve ambush in Webster recalled how his brother would race out of the house at a moment's notice at the familiar sound of his pager.

Speaking at his brother Tomasz Kaczowka's  funeral in Rochester Monday, Darek Kaczowka says there were times he'd have to get out of the way or risk being run over by the dedicated volunteer.

Hundreds of mourners filled St. Stanislaus Church for the service. Kaczowka's flag-draped casket arrived atop a fire truck. Retired Bishop Matthew Clark presided at the service.

The service was held a day after the funeral of fellow firefighter Michael Chiapperini at Webster Schroeder High School.

Both men were shot dead by William Spengler as they responded to Spengler's burning house. Two other firefighters were injured before Spengler killed himself
