An early morning check of a suspicious vehicle in a notorious North Auburn parking lot led to the arrest of a Grass Valley man on a laundry list of charges — from possession of a loaded handgun and brass knuckles to having stolen checks and 10 ounces of cannabis.

The suspect — Onesimo Uribe, 30, of Grass Valley — was also taken into custody on a “gang-member enhancement” allegation after gang paraphernalia was found in a search of a 2002 Honda Accord that had caught the attention of a Placer County Sheriff’s deputy.

According to a Sheriff’s Office Facebook post, the area in and around the parking lot of the AM/PM near the Dry Creek Road-Highway 49 intersection is known to be frequented by loiterers and people who park their cars to “camp.”

Approaching the parked Honda at 2:05 a.m. and contacting the two occupants led to a probation search by deputies.

A woman was sitting in the back seat while Uribe was in the front passenger seat. The woman was identified by the Sheriff’s Office as Stephany Trestiese Mauss, 30, of Grass Valley.

Mauss was arrested on suspicion of possession of brass knuckles, a firearm while in possession of a controlled substance, and blank checks belonging to another person.

Mauss was not arrested on the gang-member enhancement or allegations related to Uribe involving being a felon in possession of a loaded firearm.

The Sheriff’s Office report stated Mauss informed deputies that she is a teacher at Union Hill School in Grass Valley. A Journal check with the Union Hill School District showed that she is not a teacher there but was hired in September 2017 as a child-development assistant on a part-time basis.

Mauss was a child development assistant employed by the school district when the Oct. 29 arrest occurred and was placed on leave afterward, Union Hill School District Superintendent David Curry said.

During the arrest, a backpack was sighted inside the Honda. Inside the backpack was a .22 caliber handgun, a loaded magazine and 34 more .22 caliber bullets, the Sheriff’s Office said.

The vehicle search also turned up brass knuckles, four checks not addressed to either suspect and a meth pipe, the Sheriff’s Office said.

Extending the search, investigators found 276 grams of marijuana — just more than 10 ounces — and another meth pipe.

Additionally, a .22 caliber bullet was found on the floorboard of the backset, where Mauss was sitting, according to the Sheriff’s Office report.

Both suspects were booked into the Auburn Jail. Uribe’s bail is set at $155,000. Mauss is out on bail.
