Detective Acting Inspector Jessica Securo stated that the family members were believed to be part of the same household and that no weapon appeared to have been used, indicating a non-violent incident. A note was discovered at the residence, which has led authorities to treat the case as a murder-suicide. The exact circumstances surrounding the deaths remain unclear, and police are working to establish a timeline of events, including whether the incident occurred on the morning of January 30 or the previous night.
