The officers spoke with Pietro as well as her husband and referred the case to Crimes Against Children Unit detectives, who visited the home the next day.
Police say the children in the video -- a 5-year-old boy and 6-year-old girl, plus a 2-year-old boy who was not in the video -- were placed in the care of the county Department of Social Services and transferred to family members. One of the children sustained minor injuries, police said.
"The investigation shows that Pietro -- who initially told police the video was two years old -- recorded the video at the home on Cool Breeze Drive some time in the past two months," police wrote in an updated release on Tuesday. "She said she recorded the video because she hoped it would encourage her husband to come home and take care of her. She also said she was angry with the children."
