Dover Man Sentenced to Prison in Fatal Queen Anne's Crash

Queen Anne's County, MD - A 23-year-old Delaware man is heading to prison after a deadly high-speed crash on a Queen Anne's County highway last summer.

Deon Dandrade, of Dover, Delaware, pleaded guilty on June 30, 2026, in Queen Anne's County Circuit Court to Negligent Manslaughter by Automobile. He was sentenced to 10 years in the Division of Corrections, five years to serve and five years suspended.

Dandrade will also serve five years of supervised probation after his release. He was ordered to complete a mental health evaluation, perform 50 hours of community service, pay a $1,000 fine, and is prohibited from driving for one year upon release. He received 166 days of credit for time already served at the Queen Anne's County Detention Center.

The crash happened on July 22, 2025, around 9:00 a.m. on southbound Maryland Route 301 at the intersection of Route 405. Dandrade was behind the wheel of a Mazda Miata, traveling at an estimated speed between 121 and 124 mph, when his vehicle slammed into a Kia Forte driven by Mickie Lynn Mowbray, of Queen Anne's County, Maryland. Mowbray died from multiple injuries suffered in the collision.

The Maryland State Police Crash Team investigated the accident. Investigators obtained a search warrant for data from Dandrade's vehicle, which confirmed his speed was in excess of 120 mph. There was no evidence of braking before impact. Neither alcohol nor drugs were a factor.

At the time of the crash, Dandrade was an active duty enlisted airman in the U.S. Air Force. He expressed remorse and apologized to Mowbray's family at sentencing.

The case was prosecuted by Queen Anne's County State's Attorney Lance G. Richardson, who recommended the maximum six-year sentence allowed under the Maryland Sentencing Guidelines. The guidelines are not binding on a judge but are strongly encouraged by the legislature to promote consistency in sentencing across the state.

Richardson praised the work of the Maryland State Police, specifically recognizing lead accident reconstruction expert Sergeant Charles Gore.

"Although Mr. Dandrade had no prior criminal, or motor vehicle, record," Richardson said, "this tragedy was completely preventable and senseless," adding that he had to hold Dandrade accountable for his "grossly negligent conduct by recommending the maximum sentence recommended pursuant to the Maryland Sentencing Guidelines".
