The soulless son who allegedly slaughtered his elderly mother in their luxury Upper West Side building last year left behind a trail of clues pointing to his guilt, prosecutors revealed at his arraignment Monday.
Edward Asencio, 51, worriedly researched the term “elder abuse” on Google after the brutal fatal beating of his 84-year-old mom Ana Asencio — and why it was taking the medical examiner so long to come up with her cause of death, authorities said.
Manhattan prosecutors also noted that Ascencio was the only person with access to the apartment on their upscale tree-lined Manhattan street before the murder of the tragic old lady, who suffered from dementia.
“As alleged, Edward Asencio neglected and isolated his 84-year-old mother before killing her in their shared apartment,’’ Manhattan District Attorney Alvin Bragg said in a statement.
“The defendant’s alleged attack on his own mother, who relied on him for care, is abhorrent,” Bragg said.
Asencio pleaded not guilty to manslaughter and assault charges in the violent death of his mom, whose lifeless body was found face-up inside her bedroom July 17, 2023, in the building at 70 W. 93rd St., where one-bedroom apartments go for more than $5,000 a month and some units have sweeping views of Central Park.
Manhattan prosecutors said Asencio committed the “horrific act” by beating his mother “so badly” that he caused a fatal subdural hemorrhage.
The elderly woman had extensive injuries including two black eyes, bruising to her head, chest and shoulders and blood on her lips, according to prosecutors.
The medical examiner determined that Ana’s death was due to blunt force trauma, prosecutors said.
Her death was ruled a homicide six months after her body was found.
Asencio wore brown prison overalls and had his hands cuffed behind his back for the proceeding.
He has three prior misdemeanor convictions, including one for stalking a woman on the subway.
The son was remanded by Manhattan Supreme Court Judge Cori Weston.
Asencio is due back in court Oct. 23.
