Amy Steadman, 64, her daughter, Sarah Myers, 44, and four grandchildren, Harper, 13, Hudson, 11, and Gavin and Gracelynn, both 10, were found dead in their home in Mechanicville on Tuesday

The bodies were discovered Tuesday evening after a neighbor requested a welfare check, police said.

Local police say “evidence recovered during the investigation, including a handwritten note,” suggests the grandmother’s involvement.
