The suspect in the murder of 26-year-old Brittiney Cobb was arrested about 200 miles from the crime scene, after he led police on a car chase through two Virginia cities and then crashed in a tunnel, authorities say.
Rodney Stephaun Conyers, 32, of Oxon Hill, Maryland, is facing a charge of first-degree murder in Cobb's slaying, Prince George's County Police said.
Cobb and Conyers shared their home with two children, neighbors said.
Police said the killing was domestic-related. Court records show the couple was in court in 2014 related to domestic abuse.
According to a preliminary investigation, an argument between the two escalated, they said.
Officers were called to the 1100 block of Southview Drive around 4 a.m. Sunday and found Cobb inside suffering from stab wounds.
She was pronounced dead at the scene.
Conyers was arrested Sunday after Virginia State Police received a Be on the Lookout alert from Prince George's County saying the suspect was thought to be traveling through Virginia in a gold 2014 Kia Spectra sedan.
Shortly after receiving the alert, State Police say Conyers was spotted on Route 58 in Suffolk, Virginia. Officers initiated a traffic stop, but Conyers tried to flee, leading to a car chase through Suffolk and Portmouth before he crashed in the downtown tunnel, they said. The tunnel connects Portsmouth and Norfolk.
Conyers sustained minor injuries in the crash and was taken to a hospital.
He is in the custody of Virginia State Police and is awaiting extradition back to Prince George's County. State Police are in the process of obtaining warrants for the pursuit and traffic crash, they said.
A neighbor told News4 she had no indication anything was wrong.
