A Bloomington woman who had been held on suspicion of killing her husband has been released from jail.

The Hennepin County Attorney’s Office reviewed the case against the 51-year-old woman and is waiting for more information from investigators or other possible forensic evidence before deciding whether she should be charged, Deputy Police Chief Mike Hartley said late last week.

“Our detectives along with the County Attorney’s Office will continue to investigate the case further,” Hartley said, “but the decision to ultimately charge falls on Hennepin County.”

Michael S. Carpenter, 53, suffered blows to the head May 27 at the couple’s house in the 10600 block of Utica Circle and died a few hours later at HCMC, according to the Hennepin County Medical Examiner’s Office.

Officers arrived at the house about 8 p.m. after Carpenter’s wife alerted them to a domestic dispute, Hartley said. Carpenter was unconscious and suffering from upper-body injuries when he was found.

Investigators questioned his wife and jailed her late last Monday. She was released Wednesday because the time legally required to charge her had elapsed. The Star Tribune generally does not identify suspects unless they are charged.

Hartley said little about how the blows were inflicted and didn’t specify what weapon may have been used.

The deputy chief also declined to say more about what led to the violence but did say officers have been to the home previously for disputes.
