The shooting took place at around 5 p.m. Sunday, April 29, in the 13000 block of Westland Court, near Riley Street.
Deputies were sent to the scene on a report of shots being fired, which ensued after a brief argument inside the home. Several family members got out of the house uninjured, then told deputies at the scene that they had heard several shots fired before fleeing.
Upon investigation by the Sheriff’s Office Tactical Unit, three dead people were found inside the home. They were identified Monday as 34-year-old Latthida Kommona, 51-year-old Thomas Rattanavong and 43-year-old Phouthone Loy Kaiyarath. All three lived at the residence on Westland Court, according to Capt. Mark Bennett of the Sheriff’s Office.
According to Holland Township property records, the residence is owned by Rattanavong and his wife, Bounmy Rattanavong.
“All three are believed to be domestically related in some fashion,” Bennett said.
Eight people live in the home, Bennett said, including two children and six adults.
Kaiyarath, who goes by his middle name, Loy, has a child with Kommona, but there was no indication the two were ever married. Thomas Rattanavong and Kaiyarath are former brothers-in-law. Bennett said Kommona had immigrated to Holland from Laos within the past six months.
“The family strife was over the relationships in the family, but we’re still trying to determine what that strife was about,” Bennett said. “Obviously, it spun out of control.”
The argument began in an upper-level bedroom, where four adults were discussing “family dynamics and issues between the family members,” Bennett said. One adult was able to leave the room when gunshots were fired and alerted the four other people in the home to the incident. Those five individuals then left the home safely.
Autopsies on the three dead people are expected to take place Tuesday, but the victims appeared to have been killed by gunshots, Bennett said.
Kaiyarath appeared to have brought a gun to the incident. A semi-automatic handgun was recovered from the scene and no other weapons were found.
Kaiyarath’s injuries appear to be self-inflicted, Bennett said.
The triple-fatal shooting is being investigated as a murder-suicide and Bennett said there is no reason for public alarm.
Detectives are continuing to process the death scene investigation and gather information, and Bennett said there may be more information about a potential motive by Tuesday.
The Michigan State Police forensic lab is assisting with the investigation.
Although Bennett said the Sheriff’s Office is still determining the complete history of the residence where the shooting took place, a different family member had called police on Saturday regarding an argument.
“There was an argument there the night before (the shooting), where one of the family members called, but it involved different people for different reasoning, and there was no criminal activity,” Bennett said.
