The Rochester Police Department found Twenty-seven-year-old Lashanna Jenkins dead in her home on West High Terrace Saturday morning.
They say stabbing happened around 9 a.m.
"This appears to be a tragic, unfortunate case involving a domestic violence type situation," said David Moore, Rochester Police Chief.
Moore says Jenkins was stabbed several times in the upper body.
"We also understand that there were two children may have been present some time during the altercation. It is also possible that one of those young children and went to a neighbor's residence and called 911,” said Moore.
That neighbor was Anita Cooper-Molinero. She lives three doors down from the children who came knocking on her door. "They need to use the phone to call 911 and the little girl had stated that her mother's boyfriend stabbed her," said Cooper-Molinero.
"We're very interested in what the relationship was apparently there was a male individual that resides here although we have not established, we have several witnesses in terms of who lives here that we're interviewing right now," said Moore.
Cooper-Molinero is a licensed social worker who says her priority was to make sure the children were safe.
"My husband was in shock actually because he couldn't believe the little girl walked down, she had the little boy in her arms, the other little boy was by her side and she had blood on her hands,” said Cooper-Molinero.
The children are now saying with relatives.
