Federal Criminal Defense in Los Angeles
Defense in the downtown Los Angeles federal courts - from agent contact through grand jury, detention, trial, and sentencing.
Federal cases in Los Angeles are investigated by federal agencies, charged by the U.S. Attorney's Office for the Central District of California, and heard in the downtown federal courthouses. George G. Mgdesyan represents individuals and businesses through every stage of a Los Angeles federal matter - the first knock from agents, a grand jury subpoena, an indictment, a detention hearing, and ultimately trial or sentencing.
Where federal cases are heard in downtown Los Angeles
Federal criminal matters in Los Angeles are handled by the United States District Court for the Central District of California. The court's downtown facilities sit within a few blocks of one another in the Civic Center, and which building you appear in depends on the stage of the case and the judge assigned.
Knowing the layout and the day-to-day rhythm of these courthouses - where initial appearances happen, where grand juries sit, and how each judge runs a calendar - is part of preparing a Los Angeles federal case.
- First Street U.S. Courthouse (350 W. 1st Street) - the district's main downtown trial courthouse
- Spring Street Courthouse (312 N. Spring Street) - the historic U.S. Court House used for additional proceedings
- Edward R. Roybal Federal Building (255 E. Temple Street) - magistrate courtrooms, initial appearances, and Pretrial Services
The agencies and prosecutors behind an LA federal case
Charges are brought by Assistant United States Attorneys in the Central District, working with federal investigative agencies that maintain field offices in Los Angeles. By the time an indictment is returned, those agencies have often spent months or years gathering records, conducting surveillance, and interviewing witnesses.
Cases are charged by a federal grand jury sitting in Los Angeles rather than filed by a police officer. Understanding which agency is driving the investigation, and what theory the prosecutors are building, shapes how the defense responds.
- U.S. Attorney's Office for the Central District of California
- FBI - Los Angeles Field Office
- IRS Criminal Investigation - Los Angeles Field Office
- Drug Enforcement Administration (DEA) and Homeland Security Investigations (HSI)
- Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)
Arrest, Pretrial Services, and detention at MDC Los Angeles
After a federal arrest in Los Angeles, the first appearance is typically before a magistrate judge at the Roybal Federal Building. The court's Pretrial Services office interviews the defendant and reports on release conditions, and the question of release or detention is decided under the federal Bail Reform Act rather than a fixed bail schedule.
Defendants held pending proceedings are often detained at the Metropolitan Detention Center (MDC) Los Angeles, the federal facility downtown. A well-prepared detention hearing - proposed conditions, community ties, and a concrete release plan - can be decisive for what follows.
Why familiarity with the Central District matters
Federal practice follows national rules, but each district has its own local rules, standing orders, and customs. The Central District is a high-volume district with experienced prosecutors and demanding motion practice, and approaches that work elsewhere do not always translate.
George G. Mgdesyan has handled federal matters in Los Angeles and brings that working knowledge of the district's procedures to each case - from how discovery is produced to how judges handle suppression motions and sentencing.
