Jeremiah Lee Barrett, 30, was held on $2.5 million bond in the Calaveras County Jail on charges of murder and conspiracy. His brother, Leon Michael Grammer, 38, was released Wednesday morning on $30,000 bond on charges of conspiracy and being an accessory after the fact.

The Calaveras County Sheriff's Office said deputies found the bodies of three men Tuesday morning in or beside the dirt road running outside the home where Grammer lives in the town of Rail Road Flats, about 40 miles southeast of Sacramento.

Investigators said Grammer stumbled upon the three men trespassing and allegedly stealing plants from a medical marijuana garden on his property.

Grammer fired several shots at the men, then called his brother, who showed up and fired several more shots as the men tried to run away, investigators said.

No other details were released, including the identities of the victims and what weapons were used.
