A man already in custody and facing murder charges in the death of an Alexandria community activist will be charged with two other homicides in Prince George's County, police said Monday.
Tyrone Antwan Lewis, 26, will be charged with first-degree murder in the killings of a 17-year-old Potomac High School student shot outside his home last fall and a cab driver shot in 2005 as he struggled during a robbery in his vehicle. Investigators think the motive for all three homicides was robbery and were surprised that one person could be linked to all three killings.
"I can't think, off the top of my head, of someone we've charged with three separate murders," said Capt. Joseph Hoffman, assistant commander of the Prince George's County Criminal Investigations Division.
Justin Antonio Isaacs, 17, was fatally shot Oct. 10 outside his home in the 2100 block of Iverson Street in Hillcrest Heights. Police said Mr. Lewis and another man, 22-year-old Kelvin Walker, of Waldorf, Md., shot Isaacs during a robbery. Both men will be charged with first-degree murder in Prince George's County when cases they are currently being held for in other local jurisdictions are complete, Capt. Hoffman said.
The other shooting Mr. Lewis is charged with happened in 2005, when he was 19 years old.
Edmund Akofio-Sowah, 45, was shot on Jan. 26, 2005, inside his cab while in the Capitol Heights area. Officers were called to the scene of an accident in the 400 block of St. Margarets Drive and found that a cab had struck a parked vehicle. As officers checked on the driver of the cab, they found Akofio-Sowah, of District Heights, suffering from a gunshot wound to the head. He died the next day at a local hospital.
According to charging documents filed in Prince George's County District Court, police think Mr. Lewis had gotten into the cab at the nearby Addison Road Metro Station and struggled with Akofio-Sowah before shooting him.
Court records show Mr. Lewis was charged three times for robberies that all occurred within a month of Akofio-Sowah's shooting, one just 12 days beforehand, police said.
Mr. Lewis pleaded guilty in 2006 to robbery charges from two of the incidents and was sentenced to five years in prison.
It was not until earlier this year, when police were investigating the killing of Lenwood "Lenny" Harris, an Alexandria community activist whose body was discovered at the bottom of a Fort Washington well, that they were able garner enough evidence to link Mr. Lewis to the cab driver's slaying. While interviewing a longtime friend of Mr. Lewis in connection with Harris' killing, the friend described Mr. Lewis' involvement in killing a cab driver, charging documents state.
In February, Prince George's County police announced that they planned to charge Mr. Lewis, of Temple Hills, with first-degree murder in the death of Harris. After going missing from his Alexandria home in September, Harris' body was discovered in January at the bottom of a well in Fort Washington. He had been shot, and police charged three men, including Mr. Lewis, in his death.
Surveillance video showed a man, later identified as Mr. Lewis, using Harris' bank cards to try to withdraw cash from various banks in the area.
Mr. Lewis is currently in custody on unrelated charges in Fairfax County and will be officially charged with all three homicides when he is transferred to the custody of Prince George's County, police said.
Different guns were used in all three of the homicides, Capt. Hoffman said.
