The Brooklyn man accused of attacking his girlfriend with an ax and killing her pregnant friend with the weapon last weekend was charged in the slaying on Wednesday in a bed-side arraignment at a Brooklyn hospital.

Jerry Brown, 34, was charged with second-degree murder, attempted murder, assault and criminal possession of a weapon, according to court papers.

Brown, who goes by the name “the Grim Creeper” on social media, remained silent as he appeared handcuffed in a hospital bed via Skype during the arraignment, a law enforcement source said.

He did not enter a plea and will continue to undergo psych evaluation at Woodhull Hospital before his next court appearance on Friday.

Brown nearly decapitated pregnant Savannah Rivera, 20, in the ax attack early Saturday morning in an apartment at the Bushwick Houses on Flushing Avenue in Williamsburg, prosecutors alleged. She died soon after the attack.

He then swung at his girlfriend, Angela Valle, 21, hitting her on the back of the head with the ax, according to court papers. Police were alerted to the grisly scene when Valle called an Uber to the housing project after the attack, and the driver of the car called 911 instead of taking Valle to the hospital.

She is still in critical condition, according to court papers.

Brown tossed the apparent murder weapon, a Mintcraft-brand ax, in a trash compactor at the housing project after the slaying, prosecutors said.

His attorney did not immediately respond to request for comment.
