An Adams County grand jury has dropped an 82-count indictment on 36-year-old Adrian Grigg, accusing him of pulling off a series of business burglaries across Westminster and neighboring north-metro cities. Authorities say the charges trace back to alleged 2024 break-ins where cash was taken from safes and registers, marking a major milestone in what police describe as a lengthy, multi-jurisdiction investigation.
In a Facebook post on June 23, the Westminster Police Department said an Adams County grand jury returned the indictment tying Grigg to break-ins that occurred between February 2024 and November 2024, and that investigators believe he stole cash from safes or registers. The post credited help from partner agencies, including the Broomfield, Thornton, Erie, Arvada, Northglenn, Lafayette, and Brighton police departments, along with the 17th Judicial District Attorney's Office, and asked anyone with information to contact investigators.
Multi-jurisdiction investigation
Officials describe the case as the result of months of evidence-sharing between north-metro departments, a slow build that played out behind the scenes while businesses were locking up for the night. Investigators say they compared surveillance footage and physical evidence from multiple scenes before taking their findings to an Adams County grand jury.
Background and earlier Lafayette arrests
Grigg's name had already surfaced in late 2024 when the Lafayette Police Department announced it had obtained a warrant linking a suspect identified as Adrian Grigg to 14 burglaries of small businesses between Aug. 16 and Oct. 30, 2024. Lafayette's release listed multiple counts sought in that investigation and reminded readers that "charges are merely an accusation, and the defendant is presumed innocent unless or until proven guilty."
What happens next
With the grand jury indictment now in hand, the case shifts to the 17th Judicial District for prosecution. That office handles felony cases for Adams and Broomfield counties and will set arraignment and follow-up court dates as prosecutors file formal charging documents in district court.
Anyone with information about the break-ins can contact Westminster Police through the department's posted tip channels or the non-emergency line. Investigators said tips from community members and partner agencies were key to developing the case. Coverage will be updated as court filings and scheduling become part of the public record.
