Two sibling tots died a short time apart Monday morning after they were found not breathing in their Bronx home — and police have opened a homicide investigation, law-enforcement sources told The Post.
An autopsy showed that Olivia Gee, 2, died of blunt-force trauma, according to multiple sources.
“It looks like this girl was punched in the stomach. It’s a homicide investigation,” a law-enforcement source said.
An autopsy on her brother, Micha Gee, 3, will be conducted Tuesday, sources said.
Their mother’s boyfriend — a Bloods gang member who is not the father, according to police sources — was questioned at the 50th Precinct on Monday but had not been charged.
Their mother, a nurse practitioner, was put under psychiatric care at Montefiore Medical Center, sources said. The little girl and boy were her only children, sources said.
The mom, Jade Spencer, told cops both children were asthmatic, and investigators initially suspected the deaths were a result of complications from their condition.
But “two kids having asthma attacks at the same time and succumbing is virtually impossible,’’ a police source said.
Spencer, 31, told cops that she put the tots to sleep in separate beds at around 8:30 p.m. Sunday at the family’s home on Van Cortlandt Park South in Kingsbridge Heights, according to law-enforcement sources.
She said she then watched TV with her boyfriend, Novell Jordan, also 31, before going to bed a short time later, sources said.
Jordan — who police sources said has three prior arrests, including for allegedly dealing illegal fireworks and having a machete — does not live at the house but spends several nights a week there.
He told cops he checked on the kids before he was about to go to bed himself at around 1:20 a.m., found the youngsters struggling to breathe, and woke their mom, sources said.
The pair called 911, and the emergency operator told them to perform CPR, cops said.
Spencer told cops she also administered albuterol — a drug that eases asthma symptoms — to both kids, sources said.
EMS workers arrived and rushed the kids to Montefiore Medical Center, where they died at around 2 a.m., sources said.
Marks were found on the children’s necks, but they may have been from the CPR and are likely incidental, sources said.
The mom’s and boyfriend’s stories on what happened were the same, sources said. The investigation took a turn after the ME’s preliminary report came back, they said.
The family has no history with the city’s Administration for Children’s Services, but the agency launched an investigation after the children’s deaths because of the obvious “red flags’’ from the incident, according to an ACS source.
