A member of Baltimore County's tactical unit was identified Monday as the officer who killed a Reisterstown man last week when police attempted to search his home for suspects in a Howard County shooting.
The officer, Carlos Artson, was previously involved in a civil suit after he fatally shot a woman during a 2005 raid in Dundalk.
On Thursday night, Artson fatally shot Ronald Cox, who police say attacked officers with a sword, damaging Artson's protective shield. Artson, a 17-year veteran of the police force, remains on administrative duty with pay pending a review by the department.
The tactical team was trying to execute a search warrant and two arrest warrants in connection with an attempted-murder case in Howard County, police said.
Baltimore County police spokeswoman Cpl. Cathy Batton said members of the unit repeatedly identified themselves as police as they made their way to the second floor of the Reisterstown home, where they encountered Cox and two people suspected in the June shooting of a teenager in Howard County.
Howard County police identified Cox's niece, Laura Christian Karr, and her boyfriend, Donald George Peoples Jr., as suspects in the nonfatal shooting of Sterling Randolph Watts, 15.
Police arrested and charged Karr, 24, and Peoples, 21 — along with Chiquita Sketers, 21, who allegedly supplied a rifle — with attempted first-degree murder and related charges.
Karr and Peoples had been staying in Cox's home, but Cox was not considered a suspect in the case, police said.
According to charging documents, Karr and Peoples abducted Watts from his Reisterstown neighborhood June 19. They then picked up Sketers, who had a loaded long-barrel rifle, the documents said. Police said that Watts was told to get out of the car in a field off Frederick Road in Marriottsville and that Peoples shot him in the back of the head.
At bail hearings Monday, Howard County District Judge Neil Edward Axel ordered that all three suspects be held without bond.
In January 2005, Artson shot and killed Cheryl Lynn Noel, a 44-year-old Dundalk woman, in her house after police attempted to execute a search warrant for a drug investigation involving her son Matthew, who lived at home.
A civil suit brought by Noel's husband, Charles Noel, alleged that the police violated the family's Fourth Amendment rights when they executed a "no-knock" entry into the home. Police use such warrants to avoid making their presence known when dealing with potentially dangerous suspects.
The Noels lost their civil case, and a 2011 U.S. Court of Appeals ruling affirmed that the Police Department and Artson had taken appropriate action.
Neither Baltimore County nor Howard County police would say whether a no-knock warrant was used in the Reisterstown incident last week.
