A workplace argument in a Frederick medical office parking lot turned violent Thursday afternoon, leaving one man with multiple stab wounds and a 17-year-old co-worker facing adult criminal charges. Deputies were called to the 7200 block of Bank Court around 3:11 p.m. and found the victim suffering from stab wounds to his arm, chest, and abdomen before he was rushed to a local hospital.
According to the WBFF report, officials say the victim was listed in stable condition. The Frederick County Sheriff's Office identified the suspect as Darwin Orlando Martinez-Serrano, a 17-year-old from Hyattsville, who authorities say worked with the victim and got into an argument that turned physical in the parking lot. Martinez-Serrano allegedly stabbed the victim multiple times before fleeing the scene.
Investigators located Martinez-Serrano later that evening back in Hyattsville, roughly 46 miles southeast of the Frederick crime scene, a drive of about 50 to 60 minutes via Interstate 270 and Interstate 495, according to Rome2Rio. The distance meant deputies had to coordinate across county lines to track him down. He was transported to the Frederick County Adult Detention Center and now faces assault and reckless endangerment charges, per the same report.
A Medical Campus Turns Crime Scene
The parking lot where the stabbing occurred sits at the 7200 block of Bank Court, home to the FMH Crestwood medical campus, a two-story, 62,297-square-foot outpatient facility operated by Frederick Health that houses radiology, primary care, and specialty practices, according to Healthcare Real Estate Insights. It is one of the main outpatient complexes serving southern Frederick County, though it remains unclear which specific employer at the commercial complex the two men worked for.
The confrontation adds to a run of violent parking lot disputes across Frederick County this year. In July, a road-rage argument between two drivers at Loy's Station Park escalated into a machete attack that left a victim with serious injuries, as previously reported by Hoodline. Frederick recorded a violent crime rate of 406.0 offenses per 100,000 residents in 2024, above the national average of 359.1, per data cited by OpenCrime.
Why This Teen Was Sent to Adult Jail — For Now
Under current Maryland criminal procedure law, 16- and 17-year-olds accused of first-degree assault are automatically charged as adults and held in adult facilities, though defense attorneys can petition for a waiver hearing to move a case to juvenile court based on the youth's age, mental state, and treatment potential, according to the Maryland People's Law Library. Maryland Code CJ § 3-8A-03 is the statute that bypasses juvenile jurisdiction for those specific offenses. It remains unknown whether Martinez-Serrano's defense counsel will seek such a hearing.
That automatic path to adult court is about to disappear. Governor Wes Moore signed the Youth Charging Reform Act in May, and starting October 1, it will eliminate the practice of automatically charging 16- and 17-year-olds as adults for first-degree assault and certain drug or weapon charges, sending those cases to juvenile court initially instead, CBS News reported. Had this incident happened six weeks later, Martinez-Serrano's case would likely have started in juvenile court rather than adult court.
The scale of the practice the new law targets is significant. First-degree assault accounted for 19.3 percent of the 1,008 total criminal charges filed against juveniles as adults statewide in 2024, making it the second most common charge behind firearm possession, according to the Baltimore Beat. Before this year's reforms, Maryland charged more children as adults per capita than every other state except Alabama, according to legislative statements cited during the bill's proceedings.
What Martinez-Serrano Could Face
First-degree assault under Maryland Criminal Law § 3-202 is a felony carrying a statutory maximum sentence of up to 25 years in prison upon conviction, requiring intent to cause or attempt serious physical harm or the use of a deadly weapon. It is unclear whether prosecutors will pursue that top-level charge against Martinez-Serrano, who is currently facing assault and reckless endangerment counts. What sparked the argument between the two co-workers has not been disclosed, and the sheriff's office has released a photograph identifying Martinez-Serrano as part of the ongoing investigation.
