MIAMI (CBSMiami) – A toddler is dead and several other family members are being treated after being stabbed Monday evening in northwest Miami-Dade.

A law enforcement source told CBS4 that the mother of the dead toddler had been agitated throughout the day. She had been repeatedly screaming that Jesus was coming and we were all going to die from COVID.

The woman said everyone needed to be baptized immediately. She then tried to “baptize” the baby and when her 16-year-old tried to stop her, the mother stabbed the teen, police said.

The law enforcement source said the father tried to stop mom and that’s when he got stabbed. The woman then turned the knife on herself.

When police arrived at a home at NW 99th Street and NW 30th Avenue just before 9 p.m. Monday night, they were met by a 38-year old husband outside the home who had been stabbed.

“That’s when a 38-year-old male stated that his wife had stabbed him multiple times. She was inside of the house when officers attempted to gain entry into the house, that’s when they were met at the front door in the foyer area with the subject. She was taken into custody without incident, they did notice as they were taking her into custody that she did have injuries that appear to be self-inflicted,” said Miami-Dade police Detective Alvaro Zabaleta.

She was taken to Jackson Memorial Hospital.

Police also discovered that the couple’s 16-year-old daughter, who had run to a neighbor’s house to call 911, had also been stabbed. Both she and the injured man were airlifted to Jackson Memorial Hospital.

Inside the home, they found a 15-month-old girl in serious condition with injuries. She was taken to Jackson North where she died. Police said it’s unclear if the girl was stabbed or injured in another way.

“The baby’s injuries, as I mentioned before, we don’t know. We’ll go ahead and wait for the medical examiner’s office to provide that,” said Miami-Dade police Detective Alvaro Zabaleta.

Police also found there were four other children in the home at the time of the stabbing, all under the age of 11. They ran out when the violence began and were not harmed.

“All of the children are the biological children of the subject and the husband, the victim, the 38-year-old male, with the exception of the 16-year-old that was airlifted. She’s the biological daughter of the subject,” said Alvaro.

Neighbors, who described the woman as a loving mother, said they were at a loss for words.

“She’s a loving mother, so obviously she had to have snapped,” said Ronnie Williams.

One neighbor said hours before the stabbings the woman appeared “off” and was talking about the COVID-19 vaccines.

“The way she was talking to me and what she said to me about nobody should take a shot because God had revealed to her that anybody who took a shot was going to hell,” said Thelma Sloan.

“Of course, I’m very sad and I don’t think she should be punished. I think she should be given help because she was not a person who would’ve done harm to her child or anyone else.”

Authorities said the father and 16-year-old girl are in critical but stable condition and are expected to survive.
