Chilling details emerge in case of SF woman beaten to death by homeless man

Neighbors heard screams coming from Jessica Sanchez Landaverde’s San Francisco home as she fought for her life, but no one called 911 for several hours.

Instead, Sanchez Landaverde was left alone with a sadistic intruder who strangled her to death, and left her in a pool of blood on the morning of Nov. 23, according to harrowing new court documents.

The chilling timeline details were revealed by prosecutors ahead of the arraignment of Cassidy Wyatt Allen, a 45-year-old homeless career criminal who was roaming free on a deferred judgment deal for a previous assault.

The timeline of terror began around 6:10 a.m., when surveillance footage captured a man, believed to be Allen, creeping into the Ingleside neighborhood home through a window. Around 6:30 a.m., the banging and shouting was heard, and a man was seen opening the front door from the inside. Despite the noise being loud enough to mimic a seismic event, help did not arrive until it was too late.

It wasn’t until nine hours later, around 3 p.m., that another tenant returned to the Granada Avenue residence and called the police after unlocking the front door, and hearing a stranger rush toward her and lock it from the inside. The tenant ran back to her vehicle to wait for the police. The man was seen leaving around that time.

Prosecutors say the man, identified as Allen, was wearing a sweatshirt with a “Disneyland” emblem on the back. Bizarrely, he was wearing one shoe on his left foot; his right foot was bare, but the matching pair was later found at the front of the house.

When officers arrived to the scene, they found a window next to the front door open, the blinds were bent. Inside, they discovered body of Sanchez Landaverde lying on her back at the foot of the bed and soaking in her own blood. She had been brutally beaten and strangled, with ligature marks on her neck and blood around her nose and mouth. Her jaw was so badly damaged that a medical examiner later concluded it had been broken.

Allen was arrested later that night, around 11 p.m. He was found lying on a sidewalk about 1.5 miles away from the crime scene. Court documents detailed a wound found on Allen’s right hand that resembled a bite mark.

Allen’s rap sheet spans 25 years, and includes arrests for robbery, vandalism, theft and possession of drug paraphernalia. Just two months earlier in an unrelated case, he pleaded no contest to two felonies: grand theft and assault with force likely to cause serious injury.

Allen pleaded not guilty on Tuesday to a residential burglary, and a special-circumstance allegation of murder during a burglary. He faces life in prison if convicted. Allens remains in police custody without bail.
