GENESEO, N.Y. -- The Livingston County Sheriff's Office announced an arrest Friday in the killing of a Rochester man in the Town of York last month.

Police say Danielle Allen, the daughter of New York State Police Major Richard Allen, has been charged with manslaughter.

Allen was arraigned in York Town Court before Justice Walter Purtell, who remanded Allen to the custody of sheriff Thomas J. Dougherty on $25,000 cash or $50,000 bond. She is being held at the Livingston County Jail.

Marcus Postell, 22, was killed on the night of November 21. Authorities say he was stabbed.

Deputies got a 911 call from Allen on that night, calling them to Fowlerville Road. Dougherty says Allen reported a disturbance inside the home, where she had lived for less than a month. First responders transported Postell to Strong Memorial Hospital where he was pronounced dead. 

Because of the suspect's relationship to state police, they were not involved in the investigation.

“The reason is because of the relationship between Danielle and her father. We just made the decision to keep it outside the New York State Police, and I think those reasons would be obvious to someone on the outside," said Dougherty. "The perception of it alone could be critiqued and dissected and so we made that decision, and I’m proud of the investigation that our members have done. It’s been a long investigation with long hours, but like I said, we're far from done."

Police say it is still an ongoing investigation. Allen's next court date is December 6.

Purtell did not allow media in the courtroom during Allen's arraignment. It has been confirmed he is a former N.Y. State Trooper.

Judge Craig Doran, the administrative judge for the 7th Judicial District, which includes all courts in Livingston County, is aware of Purtell's decision.

He released the following statement:

“I am in the process of looking into this and speaking to the supervisor judge of the Town of York. I am aware of the situation and I am in the process of speaking with those involved. I will address this situation as fast and appropriately as I can.”
