A Southeast Washington woman was killed by a shot fired through her apartment window last night in an incident similar to seven recent shootings in that area, and a man was arrested and charged in her death, D.C. police reported.

Police sources said a man they identified only as Richie Brogsdale was picked up after a chase last night in Southeast and was charged about midnight with first-degree murder in the shooting of Yvonne Watts. Brogsdale's age and address were unknown.

Last night's shooting was the first of the recent shootings in Southeast in which the victim died. One other person was seriously wounded.

Police sources said early this morning that Brogsdale was being questioned in connection with the other shootings.

Watts was killed shortly after 8 p.m. by a shot fired through her ground-floor bedroom window from outside her apartment at 1104 Mississippi Ave. SE, police said. They said Watts appeared to be in her thirties.

The shooting occurred at time when the D.C. and Prince George's County police departments had assigned extra patrols to the neighborhoods in the city and county south of Suitland Parkway where the other shootings occurred.

Of the nonfatal shootings in those areas, five victims were female and two were male.

Residents of the area had been warned to lower curtains and blinds and shut windows as a precaution against an armed peeping Tom.

A window and curtains in the slain woman's apartment had been open slightly, according to 7th District police Lt. Charles Fonville.

Investigators said last night that it appeared, based on a preliminary investigation, that the Mississippi Avenue shooting was carried out in a manner similar to the others.

According to neighbors, Watts, the victim in last night's shooting, lived on the ground floor in the rear of a small apartment house a block or two from 7th District police headquarters.

Her mother and another woman, both unidentified, were in the victim's apartment at the time of the shooting. The other two women were in the living room and were apparently uninjured, police said.

They said the victim was shot once in the upper torso and was pronounced dead shortly afterward at Greater Southeast Community Hospital.

Lt. Fonville said officers learned of the shooting when a woman flagged down a police patrol wagon in the 1100 block of Mississippi Avenue.

An officer went to the apartment, where he found the woman with a gunshot wound in the chest.

A neighbor who said she could not identify the woman by name said she understood that the woman was the mother of three children.

The neighbor said that when she heard of the shooting, "I started hanging quilts in my window" so no potential assailant could see inside.

In previous shootings -- six of them in the District and one just over the city line in Prince George's -- a man has watched a woman alone or with a man in a ground-level apartment or office.

In most of the previous incidents, which occurred late at night or early in the morning, shots were fired through open blinds, windows or curtains.

There has been no report of the assailant entering an apartment.

In common with all of the previous incidents in the District, last night's shooting occurred in the area bounded roughly by Portland Street and Alabama Avenue SE on the north, by South Capitol Street on the west and by Southern Avenue on the east and south.

The attack in Prince George's occurred early Friday on Southview Drive.

Police said that the man charged last night was picked up after a chase that began when area residents said they spotted somebody running in the general area of the shooting.

Police also said that a gun was found in the area of the shooting, but they could not say if it was connected with the killing.

Before yesterday's slaying, police had said that they were working on a psychological profile of a possible assailant, who was described as 5 foot 6 to 5 foot 8 with a medium to dark complexion.
