New images show Texas mom Caroline Raquel Peña just minutes before she was stabbed to death — with the murder also caught in full on home surveillance cameras, according to a newly released criminal complaint.

The doorbell cam footage shows mom of five Peña, 32, with a slight smile on her face as she chats on the phone while on the doorstep of one of her now-accused murderers, Kyandra Renee Faz, 21, on June 25.

Minutes later, two sisters — Amaya “Cookie” Diaz, 19, and Kitty Mia Diaz, 21 — pull up in a black Chrysler 300, according to the complaint.

Cookie then got out of the vehicle carrying an object, believed to be a knife, and confronted Peña — allegedly stabbing her in the back, according to the complaint and footage that showed blood soaking the mom’s shirt.

Cookie’s sister and their friend then jumped in and allegedly beat the badly wounded woman before fleeing the scene, authorities have alleged.

“The entirety of the incident” was captured by a home surveillance camera near the scene, the complaint said.

It is not yet clear how the women knew each other, but Faz claimed the slain mother showed up at her house “looking to start a fight,” according to the complaint.

Just two hours after the brutal attack, Cookie and Kitty flashed twisted smiles as police hauled them off in handcuffs.

Investigators say Cookie, who appeared grinning from ear to ear as police led her to a squad car in handcuffs, stabbed Peña in the back before

Peña was reportedly driven to a local hospital by her nephew. She succumbed to the stab wounds about seven hours later, around 9 p.m., after she was airlifted to a hospital in San Antonio.

Police have not yet offered a motive for the alleged attack, which remains under investigation, a department spokesperson told The Post.

Faz and the Diaz sisters are behind bars, a judge imposing a $5 million bond for each of the suspects during their first court appearance Friday, when they all requested court-appointed attorneys.
