A Canton woman was arrested Sunday on an obstruction of justice charge in the case of a nine-months pregnant woman whose body was found in a park, The FBI said.

Agents and Stark County sheriff's deputies arrested Myisha Ferrell, described as a former classmate of the man being held for arraignment on murder charges, after breaking down the door of her apartment and searching it Saturday night, FBI agent Scott Wilson said.

The sheriff's department refused to discuss anything about the arrest, saying any information made public would hurt their case. Ferrell was to be arraigned on Monday, Wilson said.

Summit County Medical Examiner Lisa Kohler on Sunday identified the body found in Cuyahoga Valley National Park Saturday as that of Davis, with the dead fetus still inside her womb.

Davis' boyfriend, a police officer, was arrested and was to be arraigned on murder charges Monday, authorities said. Investigators have refused to comment on the circumstances surrounding the discovery of Davis' body and the arrest of Bobby Cutts, Jr., of North Canton.

Stark County sheriff's deputies with a search warrant on Saturday night used a battering ram break down the door of the apartment of a high school classmate of Cutts. Justin Lindstrom, 27, an upstairs neighbor of Ferrell's, said the officers spent two hours searching before leaving with several brown paper bags filled with items and bottles of bleach from the basement.

Wilson would only say that Ferrell's arrest was connected to the Davis case. He would not describe what the deputies seized or say how she was involved.

Lindstrom said he had not seen the downstairs tenant on Saturday or Sunday and rarely spoke to the woman, except to ask her to turn her music down. He said he didn't notice anything out of the ordinary around the time Davis disappeared. Lindstrom said Ferrell lives with her 11-year-old daughter.

Lindstorm said the two of them never hit it off.

"She's not exactly your ideal neighbor. She and I haven't gotten along since day one," said Lindstrom, who moved into the building in January. He said she had parties every night.

"We're talking carloads at a time - four and five carloads -and until 3 or 4 in the morning," Lindstrom said.

Ferrell worked at a local Denny's restaurant until quitting her job on Friday, Lindstrom said. A manager at Denny's, who declined to give his name, confirmed that Ferrell had worked there but declined to comment further.
