The Connecticut mother who was found dead in her home this week along with her three children had strangled the children before taking her own life, police said Thursday.

Sonia Loja, 36, was identified by Danbury police as the woman found dead of suspected asphyxiation hanging in a single-family home on Whaley Street, where officers responded for a welfare check around 6:30 p.m. Wednesday.

Loja’s three children, identified as 12-year-old Junior Panjon, 10-year-old Joselyn Panjon and 5-year-old Jonael Panjon, were also found dead at the residence.

“Pending an official autopsy, preliminary findings indicate that Ms. Loja strangled all three of her children before committing suicide,” Danbury police said in a statement to The Post. “However, this remains an active investigation.”

Loja and her three children lived in the house with two other adults who were not there when police arrived Wednesday. Since then, they have been informed of all four deaths, police said.

Sonia Loja, 36, was found dead on suspicion of suffocation from hanging.

Police found the grisly scene at this home in Danbury, Conn.

Police said “preliminary findings indicate that Mrs. Loja strangled her three children.”

Autopsies were scheduled to take place Thursday morning.

“Our thoughts and prayers are with the family and friends of the victims,” ??department officials said in a statement.

“In the coming days, counseling and mental health services will be provided through collaboration with Danbury Public Schools and the City of Danbury,” Esposito said in a statement. “Our community grieves for the innocent lives that were taken from us. We will get through this together.”
