The estranged husband of a missing Staten Island schoolteacher teamed with his six-months pregnant girlfriend to kill his wife, burn her body and hide it in a storage locker, prosecutors said Friday.

Michael Cammarata, 42, and ­Ayisha Egea, 41, who is carrying his child, were charged with second-degree murder, tampering with evidence and concealing a human corpse in the death of Jeanine Cammarata.

Both were held without bond.

Sometime between Saturday and Monday, the couple allegedly killed Jeanine Cammarata, 37, at their home in Rockaway Beach, Queens, then burned her body so badly that the medical examiner needed dental records to prove it was her.

They threw her remains in a trash bag and carted it into a storage unit in Staten Island’s Arden Heights section using one of the facility’s large bins, prosecutors and law enforcement sources said on Friday.

Michael Cammarata and a person believed to be Egea were allegedly caught on video as they lugged what appeared to be a large object, a police source said.

Cops found her body beside a slew of air fresheners apparently set up to hide the putrid smell, a law enforcement source said.

Jeanine Cammarata, who taught at PS 29 on Staten Island, was last seen Saturday and had told loved ones she was going to pick up the two children she had with Michael Cammarata, but the beloved teacher never made it back.

Jeanine and Michael Cammarata had been separated since May 2016 and had a history of domestic violence incidents while together.

The two were in the middle of a custody battle over their children — a 3-year-old boy and 7-year-old girl — when she vanished. Jeanine Cammarata also has another child from a different relationship.

Jeanine Cammarata had just served Michael Cammarata divorce papers two days before she disappeared, and the two were expected in Family Court on Monday for a hearing.

Her boyfriend, who lives on Staten Island, had reported her missing on Tuesday morning.

A friend of Egea’s told The Post that Egea wasn’t responsible for the murder and that Michael Cammarata was behind the grisly crime.

“She didn’t do it. The man admitted to doing it by himself. The police are trying to charge her saying she knew about it, and that’s why she is being charged,” said the friend, Enzo Ramos.

“She will be beating the charges and released. She was home the entire time, and the cameras of the complex prove she was not with him.”

Jeanine Cammarata’s friends first became worried on Monday, when they received a flurry of strange text messages that were sent from her phone but which they didn’t believe came from her.

Jessica Pobega, who says she is one of Jeanine Cammarata’s closest friends, replied that she was going to call the police.

Pobega mourned her friend’s death on Friday and slammed the duo charged with her murder.

“May they suffer in the 10th circle of hell,” Pobega wrote on Facebook. “I will miss you forever … I will make sure they pay … I will make sure that they see my face at that trial.. you will have justice …

“They had no right to take you away like that … you deserved the world.”
