A New York woman charged with attempted murder in the deaths of two persons found in a house near Temple Hills earlier this month remained in custody without bond yesterday while prosecutors waited for the Maryland medical examiner to determine what caused the deaths.

Prince George's District Court Judge Sylvania Woods ordered Ann Marie Spence, 28, to remain in custody at the county detention center and scheduled a second bond review hearing for June 5.

Spence had been charged Friday with the attempted murders of Dennis White, 33, and his daughter Donna, 15, whose bodies were found May 5 in their house at 5319 Old Branch Ave.

Police later found more than $1 million in cash stashed in two suitcases at the house, money that investigators claim was earned through illegal drug sales.

Police said they did not charge Spence, a former girlfriend of Dennis White's, with murder because the medical examiner has been unable to determine what killed the Whites.

Assistant State's Attorney William Manico told Woods that the medical examiner was unable yesterday to say when final autopsy results would be available. Manico said that Spence allegedly told county police that she mixed cocaine and oven cleaner in Dennis White's food. "They don't know whether it was the cocaine or the [oven cleaner]" that killed them, Manico said.

Susan E. Spiess, Spence's attorney, told Woods that the medical examiner already had had custody of the Whites' bodies for three weeks and that keeping Spence in jail for 10 more days would prevent her from gathering alibi witnesses who could place the woman in New York when the crimes occurred.
