The 26-year-old man charged in the so-called peeping Tom slaying violated his parole this summer when he was charged with indecent exposure, but the D.C. Parole Board did not return him to prison because it decided he was not a threat to the community.

Ricky Brogsdale of 3633 Sixth St. SE has told police in a videotaped statement that he killed three people in the last six weeks and participated in a fourth slaying, according to prosecutor June M. Jeffries.

Police said yesterday that they strongly believe Brogsdale also is linked to six other peeping Tom shootings in a Southeast neighborhood since early September. A seventh such incident occurred just over the Prince George's County line.

Brogsdale was paroled from prison May 11 after serving time for carrying a pistol without a license. In June, he was arrested on a charge of indecent exposure to which he later pleaded guilty.

Gladys Mack, head of the D.C. Parole Board, said the board decided not to return Brogsdale to prison after checking with his parole officer and a forensic psychiatrist who had met with him during his parole.

"It was a minor misdemeanor, and he seemed to be making a satisfactory performance on parole," Mack said. "He had lived up to his other parole conditions, including the condition that he report regularly to a psychiatrist. He had not tested positive for drugs in a urine test. We checked all the facts."

"We make 7,000 judgments a year," Mack said. "Based on our judgment, we had no reason to believe that Mr. Brogsdale should be removed from the community."

But police sources expressed surprise that the board did not revoke Brogsdale's parole, considering his arrest record, which includes arrests for drug possession, armed rape and indecent exposure.

Brogsdale, who is being held without bond, has been charged with first-degree murder in the slaying of Yvonne Watts. Watts was shot to death Saturday night by a gunman poised outside her ground-floor apartment window at 1104 Mississippi Ave. SE. Police arrested Brogsdale about five blocks away.

Brogsdale also has been charged by police with first-degree murder in the Sept. 6 shooting of Steven Wilson, 28, of 1708 W St. SE. Sadie Turner, Wilson's 27-year-old girlfriend, was wounded in the incident. According to police, Brogsdale said he believed his sister had been fatally beaten by Wilson.

Police said they have linked Brogsdale to the shooting death of Myers Jackson of 1853 Alabama Ave. SE, whose body was found on Suitland Parkway just west of the Southern Avenue overpass on Sept. 5. They also consider him a suspect in the shooting death of 17-year-old Angela Shaw of 3002 Massachusetts Ave. SE, whose body was found in a wooded area in the 2300 block of Good Hope Road SE on Sept. 20.

Police and prosecutors have said that evidence in these cases, which are still under investigation, will be submitted to a grand jury.

Police sources said that while Brogsdale was on parole, he worked about a month for the D.C. Department of Public Works. But police said that when he was arrested, he was unemployed. An individual on parole must be employed or actively seeking a job.
