Britton has been behind bars for over 30 years. Hudson Valley Post recently reported Britton was set to be released in a few weeks.

In March 1989, Britton, then 16, shot and killed his father, Dennis, 44, 42-year-old mother Marlene and 8-year-old brother Jason in their Town of Poughkeepsie home.

He also shot his sister Sherry in the stomach and head. Sherry survived the shooting.

The New York State Department of Corrections and Community Supervision planned to grant Britton parole as early as April 10.

"The District Attorney's Office has consistently opposed the release of Mr. Britton and was not given notice of the Parole Hearing which took place earlier this month," Weishaupt stated.

Dutchess County District Attorney's Office shared with the parole board Facebook posts made by Britton last November.

"These postings and messages are alarming for several reasons, not the least of which are statements attributed to Mr. Britton directed at his sister saying, 'You should've played nice,' that she is 'complicit in the cycle of hurt' because she will not forgive him; and a claim in Facebook posts that his sister participated in part of these heinous crimes," Weishaupt wrote in his letter. "These statements clearly demonstrate that Mr. Britton still refuses to acknowledge responsibility for his actions," Weishaupt wrote.

Late last week, the Board of Parole decided o suspend Britton's release date.

"The evidence submitted demonstrates that Mr. Britton remains a danger to the only surviving victim and his release would be incompatible with the welfare of society," Weishaupt told Hudson Valley Post in an email. "We urge the Board of Parole in the strongest possible terms to deny parole for Mr. Britton. We are confident after serving Mr. Britton with the evidence and after a full and thorough review is conducted his parole will be denied."
