On Sunday, officers at the San Joaquin County Honor Farm Facility say they saw a person throw a package of “contraband” over the fence onto the grounds of the facility, get into a car, and drive away.

Officers searched the area where the item was thrown but were unable to locate the item in the tall grass. They brought in a law enforcement K9, Sage, who found the package.

Officers opened the package, which they say contained 28.4 grams of a green leafy substance believed to be drugs and 4.4 grams of tobacco. Also located in the packages were a lighter and two AA batteries.

An investigation found the drugs were intended for inmate Eric Ypon. He was allegedly found to have a controlled substance during his time at the honor farm, which is a felony.

Ypon has since been transferred to the main jail where he is waiting to be formally charged.
