The Mecosta County Sheriff's Office is now reporting that one person was killed in the hostage situation that lasted 11 hours. They also say three people were sexually assaulted.
The standoff started shortly after 8:30 p.m. Thursday when deputies responded to a call of shots fired at a mobile home park in Rogers Heights.
After deputies arrived, they heard a woman inside the home say "he has hostages." Deputies reported that a man inside sounded "extremely agitated" cursing at deputies and saying police were the reason he was in this position.
Family members at the scene told WOOD-TV a man broke into the house and ordered everyone to take their clothes off.
A hostage negotiation team established communication with the suspect but had limited response. At one point, the Sheriff reports approximately an hour and a half passed with no communication.
The suspect, who has been identified as Duncan Willis, agreed to release five of the six hostages at 4:42 a.m., eight hours into the standoff. Those hostages were two 7-year-old boys, a 10-month-old girl, and two adult woman.
While interviewing the hostages, deputies learned there was a 58-year-old woman dead inside the home. The woman has been identified as Kathleen Hawley of Morley.
Just under two hours later, the final hostage, a woman, was released. Willis then surrendered without incident.
WOOD-TV reports three people were taken to the hospital for treatment.
Willis was charged with felony murder, six counts of criminal sexual conduct, kidnapping, carrying a dangerous weapon with unlawful intent, felony firearm and habitual offender second offense.
Police also believe he was intoxicated at the time.
WOOD-TV reports Willis has been convicted of three domestic violence incidents in the past.
They also say the majority of the people involved are friends and live together in the residence. Police said Willis was an acquainteance of one of the female hostages.
