ANNAPOLIS (AP) A convicted sex offender has been indicted in a 13-year-old rape case based on what prosecutors say was a genetic match in a Maryland State Police DNA databank.
The Anne Arundel County grand jury indictment, handed down Friday, was the first time a match was made in a cold case within the Maryland database, lab director Louis Portis said.
The databank of 5,000 DNA samples from sex offenders is expected to double in size by the end of the year, Mr. Portis said, and an application for a federal grant for examining cold cases is in the works.
"We are rapidly building and we expect many more," Mr. Portis said.
Anne Arundel County police, who have been revisiting unsolved cases using DNA, sent a DNA sample to the state police lab, which officially opened last year. Police heard back last month, said Kristin Riggin, a spokeswoman for the State Attorney's Office.
The grand jury indicted Robert Marshall Eiseman, 41, on a charge of second-degree rape and five related charges stemming from the assault on a 22-year-old Cape St. Claire woman who was attacked on Dec. 1, 1988, as she returned home from work at a Parole bar.
News reports at the time said the woman was attacked first in her front yard and again under her porch. Police first suspected another man, who was charged in another case. The two cases were among five sexual assaults that occurred between October and mid-December 1988 and that police attributed to two men.
Neither Mr. Portis nor prosecutors would discuss details of the case.
Prison officials said records show Eiseman has been serving a 20-year sentence for rape and attempted murder since 1989 after being convicted in Montgomery County.
Last year, Gary William Pescrillo, 44, became the first person charged with a sex crime in Maryland based solely on a "hit" from a national DNA computer database. Mr. Pescrillo, who lives in Chicago, faces charges of sexual assault and burglary from a 1989 attack in Linthicum, Md.
