District attorney investigators are working to determine if Manteca Councilman Dave Breitenbucher’s shooting of his stepson early Thursday afternoon was in defense.

Landon White, 31, was in critical condition following the 12:28 p.m. shooting in the 100 block of Yolo Street that ends near the Spreckels Park BMX track.

Breitenbucher told Manteca Police his stepson attacked him and threatened to kill him in a confrontation inside his home.

 White, a 2013 Manteca High graduate, sustained a gunshot wound to the abdomen.

Breitenbucher suffered a laceration to his head.

The council called 9-1-1 to report the shooting.

Both were taken to area hospitals.

Police said Breitenbucher fired a personal firearm.

White is not a resident of Breitenbucher’s home.

Manteca Police Chief Stephen Schluer said the San Joaquin County District Attorney’s office is involved in the investigation as is standard in cases where self-defense may be involved.

Once the DA’s investigator completes their report, the DA’s office will determine whether charges will be filed.

Breitenbucher last year married White’s mother.

Police said they are looking into the relationship between Breitenbucher and his stepson.

 Breitenbucher is a retired Manteca Fire captain.

He is currently in his sixth year serving as a council member for Area 3.

Breitenbucher for years coached the Manteca High swimming team and then the Sierra High water polo team.

The council devotes a good portion of his free time volunteering with the outreach effort to try and get the homeless off of Manteca streets.
