A man was taken into custody Sunday after Harris County Constable's deputies found him asleep behind the wheel of a running vehicle with a handgun resting in his lap, according to a preliminary report. The arrest happened in the 15300 block of Boulder Hollow Lane, and the man now faces charges of driving while intoxicated and unlawful carrying of a weapon.
Constable Mark Herman's office, which covers Precinct 4 in northern Harris County, posted details of the stop on Facebook Sunday afternoon. Deputies reported finding the adult male asleep inside the vehicle while the engine was still running, with the handgun in plain view on his lap. He was suspected of driving while intoxicated and was subsequently arrested on both the DWI and unlawful carrying of a weapon charges, per the post.
Precinct 4 routinely shares these kinds of real-time updates through its C4 NOW mobile app and social media channels, giving northern Harris County communities like Cypress, Spring, and Tomball immediate word of local arrests and traffic incidents, the constable's office has noted.
Why Sleeping Behind the Wheel Still Counts as Driving
It might seem odd that a parked, sleeping driver can be charged with DWI, but Texas courts have long treated this scenario as a form of driving. Under case law interpreting Penal Code Section 49.04, officers can arrest an intoxicated person found asleep in a parked vehicle with the engine running, because courts define “operating” a vehicle as maintaining actual physical control that would let someone use it, according to Mark Diaz Law. Judges weigh factors like where the keys are, whether the person is in the driver's seat, and whether the engine is on to decide if someone had that control.
A baseline first-offense DWI in Texas is a Class B misdemeanor, carrying a mandatory minimum of 72 hours in jail, up to 180 days behind bars, and fines as high as $2,000, per the Joyner + Joyner Texas Law Firm. That charge can escalate to a Class A misdemeanor if the driver's blood alcohol concentration reaches 0.15% or higher. Separately, carrying a handgun while intoxicated generally falls under Unlawful Carrying of a Weapon, a Class A misdemeanor punishable by up to a year in county jail and a fine of up to $4,000, according to Blass Law's breakdown of Penal Code Section 46.02.
A Familiar Pattern for Precinct 4
This is not the first time Precinct 4 deputies have come across an intoxicated driver with a firearm nearby. Just days earlier, constables arrested a driver on FM 1960 Road West on felony DWI charges after finding three young children and a firearm inside the vehicle during a traffic stop, as Hoodline previously reported. In December, deputies arrested a driver on Gosling Road who faced DWI and unlawful weapon carrying charges after officers recovered three firearms from his vehicle. And back in March 2024, Precinct 4 deputies found a driver passed out behind the wheel in a moving lane on FM 1960, who was later charged with DWI and unlawful weapon carrying after testing at three times the legal blood-alcohol limit.
The recurring combination of impairment and firearms in Precinct 4's jurisdiction reflects a broader problem across the county. Harris County recorded more than 3,500 alcohol-related traffic crashes in a single year, according to an analysis of Texas Department of Transportation data by Houston Personal Injury Attorneys, making it the highest-ranking county in the state for drunk driving accidents. Statewide, Texas recorded 22,087 alcohol-related traffic crashes in 2025, resulting in 865 fatalities and 2,126 serious injuries, based on Texas Department of Public Safety figures relayed in a law enforcement broadcast on Facebook.
Open Questions in the Boulder Hollow Lane Case
The constable's preliminary report does not include the suspect's identity, age, blood alcohol concentration results, or whether he refused chemical testing. It's also unclear which court will handle the case or what bond conditions, if any, have been set. Those details typically emerge once county prosecutors and judicial officers formalize charging documents following an arrest like this one.
Harris County continues to lead the state in overall roadway fatalities as well, recording 579 traffic deaths in 2024 out of 4,150 statewide, according to state Crash Records Information System data cited by Hamilton Wingo. That backdrop underscores why Precinct 4 continues to publicize arrests like the one on Boulder Hollow Lane as part of its ongoing enforcement efforts across Cypress, Spring, and Tomball.
