PORTLAND – A Harrison woman charged with murder in connection with the death of her baby is seeking to suppress evidence and statements at her trial.

Pamela Henderson, 44, of 12 Mill St., filed a motion in Cumberland County Superior Court in an effort to keep out of the courtroom statements she made about the May 5 death of her 3-month-old son, Zachary.

Henderson’s motion claims she was interrogated by police in violation of her constitutional rights and that her statements were not made of her free will and rational intellect.

She also filed a motion aimed at not allowing evidence at trial that resulted from a police search of her home and vehicle.

That motion claims the search warrant police used was “overbroad, dependent on untrustworthy information and otherwise deficient.” It also said that items not listed on the warrant were seized from her Mill Street apartment.

Police reportedly seized wet towels from a hamper, damp baby clothes, several baby blankets from the crib, a computer, a handwritten note, a knife and pills.

Henderson, through her attorney, Amy Fairfield of Kennebunk, also filed a motion seeking information from prosecutors about any rewards, promises or inducements they might have offered to witnesses in exchange for their testimony at trial. Those could include discussions about changes to a witness’ pending criminal charges, probationary or bail matters in exchange for his or her cooperation.

Justice Roland Cole ordered Henderson to undergo an evaluation that included a psychological assessment. Records of that report have been sealed.

Henderson was indicted May 9 on a murder count.

She reportedly told Zachary’s father: “I’ve done something bad … I’ve killed the baby,” court records said.

Police said Henderson took pills and cut her wrist after the baby’s death. She told police she fell asleep with Zachary in the bathtub and awoke to find him dead underwater, court records said.
