BATON ROUGE, La. — Brad Garafola, one of three law enforcement officers killed by a gunman in an ambush, returned fire to the end.

Garafola, a 45-year-old East Baton Rouge Parish sheriff’s deputy, will be laid to rest Saturday, a day after the funeral service for Baton Rouge police Officer Matthew Gerald, 41. Funeral services for the third officer slain, 32-year-old Montrell Jackson, are slated for Monday.

The three officers were killed by 29-year-old gunman Gavin Long; three other officers were wounded. Long was killed by police.

Garafola’s boss, East Baton Rouge Sheriff Sid Gautreaux, described to reporters how he could see Garafola on surveillance video, firing at the gunman as bullets hit the concrete around him. “My deputy went down fighting. He returned fire to the very end,” the sheriff said.

Garafola’s friends described him as a man committed to public service and devoted to his family.

He leaves behind a wife and four children.
