She never came back to pick the oldest daughter up, leaving her friend worried and puzzled.
Rosa-Soares who was 32, had struggled lately according to her family and friends and she had talked about suicide.
On Friday morning, police found Rosa-Soares body and that of her 9-year old daughter hanging in the basement of her home.
Plymouth, Massachusetts District Attorney Timothy Cruz said they were investigating the deaths as homicides.
It was too early to make a determination whether the two deaths had been a murder suicide, but there was not any threat to the general public said police.
Rosa-Soares father Jose Rosa said I feel mad, dead and pissed while standing with family members who had clustered in different groups with some crying while others stood silent smoking.
The two bodies were found just prior to 10:00 am after a friend of the family had called authorities for help.
Rosa said the family friend had called to find the reason that Rosa-Soares did not return, Cruz said what had taken place over the past couple of days was under investigation.
Marley would have been 10 next week, according to documents in the court.
Cruz said that written information had been discovered in the home, but more investigation was needed prior to authorities releasing the name of who wrote it.
Jose Rosa spoke about being worried that his daughter was not able to care for the children. He said he saw her kick and slap them.
Rosa added that he had called authorities at the child welfare repeatedly to request they take away the children from her though it was still unclear as to what agency he had spoken to.
Officials from the Massachusetts Department of Families and Children had not received reports resulting from what had taken place.
