OLIVEHURST — The Yuba County Sheriff’s Office released details this week regarding two separate criminal investigations that led to arrests in Olivehurst and Dobbins involving alleged drug manufacturing and the possession of a homemade explosive device.
The initial enforcement action occurred on Oct. 13, when Yuba County sheriff’s deputies executed a probation search warrant at a residential address on the 1100 block of Holly Avenue in Olivehurst. During the search of the property, detectives discovered an active illegal drug manufacturing process.
In a public statement released on Sunday, Sheriff’s Public Information Officer Shaum Holkko reported that detectives located an operation producing Dimethyltryptamine, a illegal substance commonly known as DMT. Holkko stated that DMT is a powerful psychedelic compound that produces intense hallucinations when introduced into the body. Following the discovery at the Holly Avenue home, deputies arrested 43-year-old Keith Lowman.
Lowman was transported to the Yuba County Jail, where he was formally booked on multiple narcotics-related charges stemming from the search. Official court records show that Lowman subsequently entered a plea of not guilty to all charges brought against him.
Following his initial court appearance, Lowman was released from custody on Oct. 15 on his own recognizance pursuant to an order issued by the court. According to Holkko, Lowman is scheduled to return to court for his next hearing on a pending November court date.
In an unrelated case announced by the agency, members of the Yuba County Sheriff’s Office Problem Oriented Policing team conducted a separate search warrant operation on Oct. 15 on New York House Road in Brownsville. That investigation resulted in the arrest of 58-year-old Wilber Cummings of Brownsville.
Public jail records indicate that the specific physical location of the arrest of Cummings took place at 14741 Wolf Mountain Road in Grass Valley. Holkko later confirmed that the Grass Valley location listed on the booking documentation was an operating commercial business.
Following the search and subsequent arrest, Cummings was booked into the Yuba County Jail on charges that include the possession of an explosive device in a public place, as well as narcotics offenses. Holkko disclosed that law enforcement officers accused Cummings of possessing methamphetamine during the incident.
Jail records confirm that while Lowman was released pending his next court appearance, Cummings remains incarcerated in the Yuba County Jail following his arrest on the explosive and drug allegations.
