An 18-year-old woman and five men were indicted on murder and conspiracy charges yesterday in the December contract murder of the woman's husband, Michael Hoffmann of Suitland.

The woman, Donna Jean Hoffmann, allegedly paid four men $100 to help her and her lover kill her husband of three months, according to Prince George's County police.

On Dec. 15, Hoffmann allegedly drove her husband to Aquasco where the five men, including her lover, were waiting. He was then shot in the presence of all six suspects, police said, and his body dumped into a creek.

In addition to the murder and conspiracy to commit murder charges, Hoffmann was indicted on charges of being an accessory after the fact of murder and kidnapping, meaning that she is accused of driving her husband to the scene of his slaying and helping dispose of his body.

Mrs. Hoffmann's lover, John Penkert III of Upper Marlboro, was indicted on charges of being an accessory after the fact of murder, robbery and theft from Michael Hoffmann, in addition to murder and conspiracy.

Four other suspects were also indicted on murder and conspiracy charges, and three were indicted on other charges. They are Stephen Troese Jr., 18, charged with accessory after the fact of murder, robbery, theft and carrying a rifle; George Harvey, 20, charged with false imprisonment, robbery, theft and carrying a rifle; Jeffrey Whittaker, 18, charged with false imprisonment, and Michael Naquin, 21.

In a rare move, Judge Jacob Levin issued a gag order yesterday, requesting lawyers, witnesses and law enforcement officials not to talk about the case. Defense attorneys requested the order and prosecuting attorneys did not object.
