An Arizona mom is accused of killing her 17-month-old son before callously wrapping the infant’s body in a blanket and dumping it in a hotel freezer for weeks, according to a report.

Ochra Manakaja, 31, was arrested Sunday morning after she dialed 911 to report the boy was dead at the La Quinta Inn & Suites in Flagstaff, court documents obtained by AZ Family show.

“I killed him,” she allegedly told dispatchers before abruptly hanging up, according to the report.

The child’s body was found bundled in a blanket, covered in plastic, taped, and stuffed inside a clear box in her hotel room freezer, where it had reportedly been for two weeks, according to police.

The twisted mom’s 9- and 7-year-old children were also found inside the room, but both were unharmed, authorities said.

Manakaja allegedly told police she was fed up on April 29 and threw the fussy, crying child into his crib.

She said he later wasn’t “acting like himself,” began vomiting, stopped eating and appeared weak and pale, according to the court documents.

The boy spiked a fever the next day, but the heartless mom, who has a lengthy criminal record, allegedly refused to take him to the hospital or notify any family members, fearing she would get in trouble.

When she checked on him next, Manakaja found the victim unresponsive, lying face up with his eyes closed. She frantically used a cold rag to wake him up, but when he didn’t, she wrapped him up and stashed him in the freezer, court docs show.

The warped mom – previously convicted for aggravated assault with a deadly weapon and DUI – allegedly told cops she “f–ked up” and that her son didn’t deserve to die.

The child’s cause of death is unknown.

She was hit with first-degree murder, child abuse and concealment of a dead body charges.

Manakaja is being held on a $1 million bond at Coconino County Jail.
