Minnesota prosecutor said Tuesday she will seek the release of a man imprisoned 27 years for murder after a key witness has recanted her testimony and told authorities she committed the crime.

Hennepin County Attorney Mary Moriarty said she supports the effort by attorneys for Bryan Hooper Sr. who are asking for a judge to vacate his conviction.

At a press conference, Moriarty apologized to Hooper’s adult daughter, Bri’ana Hooper. Moriarty was not with the office in 1998.

Hooper now 54, was convicted by a jury at trial in 1998 of premeditated murder, felony murder while committing burglary and felony murder while committing kidnapping in connection with the death of Ann Prazniak, 77. He received three life sentences with the possibility of release after 30 years. He is in prison in Stillwater.

The woman who prosecutors say has confessed is in prison in Georgia for an assault-related crime and will be released in about four years.
