DEDHAM, Mass. — Police found sketches of the park area where Dirk Greineder's wife was murdered, one of which includes a stick figure of her body, during a search of the renowned doctor's house, an officer testified.

Wellesley Detective Jill McDermott took the stand for nearly three hours, recounting three different searches of the couple's split-level home in the aftermath of Mabel Greineder's murder on the morning of October 31, 1999, in a nearby wooded suburban park.

Although she testified about the seizure of several pieces of evidence, McDermott's statements concerning the drawings of the crime scene attracted the most attention from lawyers for both sides and the most interest from the jury.

"They had the Morse's pond area, the circle area, some path areas were drawn out," the detective recounted, causing several jurors to crane their necks forward and perk up their ears. "And one picture even had a stick figure drawing where May Greineder's body was."

The prosecution has charged Greineder, 60, with first-degree murder, claiming the killing was the result of "an elaborate plan gone awry" by the doctor to kill his wife while on a walk in the secluded park. Prosecutor Richard Grundy may argue that the drawings are evidence of a premeditated killing.

Greineder claims that he separated from his wife during the walk after she hurt her back, and that an anonymous assailant attacked her while he was away. Defense attorney Martin Murphy told a grand jury last summer that his client made sketches of the park area for him after his wife's slaying to help explain the sequence of events.

On the fourth day of testimony, McDermott told the jury that she recovered the drawings from a waste basket in the Greineder basement during a search of the premises on November 12, 1999. Under cross-examination from Murphy, the detective acknowledged that she did not find the pictures during two previous searches of the residence, conducted during the afternoon and night after the crime.

McDermott, working her first homicide case as a detective, also told the jury about several statements Greineder made after she and another officer had taken him to a police station after the murder.

"'I told you everything. I'm not hiding anything. You ask me for my clothes and it scares me,'" she recalled Greineder saying after officers asked to take his blood-stained windbreaker, shirt, jeans, and sneakers.

The officer also testified about the reaction of Greineder's daughter Britt after she met her father at the police station.

"What happened between you and mom? Did something happen?" McDermott remembered her asking.

Britt, Kirsten, and Colin Greineder have publicly professed belief in their father's innocence.

State trooper Julia Mosely also took the stand and testified about documenting the murder site as part of a crime scene services team. In addition to taking close to 50 photographs, most of which were entered into evidence, Mosely also worked in a forensics lab to check items found at the crime scene for fingerprints.

She could not find identifiable prints on several "Ziplock" bags, a trash bag, a loaf pan, and a pair of surgical gloves, all of which were found near the crime scene.

Although a lack of fingerprints is usually good news for defendants, in this case the spotless quality of the evidence may have helped the prosecution. If the items were trash that was discarded near the site by chance, rather than utilized as part of a murder plan, they would likely have carried the prints of their previous owners.

The significance of the printless items was contested heavily by each side. On cross-examination, Mosely admitted to Murphy that one can carry items with bare hands and not leave prints. On redirect, Grundy tried to get the trooper to speculate as to the likelihood that this would happen.

This testimony prompted Murphy to recross Mosely, during which she concluded that prints would "probably" be left by carriers of the items. When the defense attorney finished with the Mosely, Grundy rose halfway out of his chair as if he was going to question Mosely for the third time before sitting back down again.

Mosely's boss in the crime scene services unit, Deborah Rebeiro, also took the stand briefly before court adjourned for the day. She documented and analyzed footprint evidence at the scene and will resume testifying at 9 a.m. Thursday about a set of footwear marks that may have been made by the killer as he dragged the victim's body into the woods.

The trial is being broadcast on Court TV.
