New Details Revealed About Deadly Home Invasion In San Francisco

SAN FRANCISCO, CA — New details have emerged in connection with a home invasion burglary on Sunday in San Francisco that left one person dead.

Prosecutors say Cassidy Wyatt Allen appears to have used a window to enter a home in the 200 block of Granada Avenue just before 3 p.m.

When another tenant arrived at the residence, she heard someone inside run to the door and lock it, the San Francisco County District Attorney's Office said.

"Terrified and alarmed, she ran back to her vehicle and called 911," prosecutors said.

Allen had already left by the time police responded to the scene, prosecutors said.

When officers arrived, they noticed a window at the residence was open with the interior blinds partially bent, prosecutors said. The door, meanwhile, appeared "undisturbed," prosecutors added.

After entering the home, the officers saw a person lying on her back at the foot of a bed with her pointed towards the bedroom door, prosecutors said.

Officers tried resuscitating the victim by administering CPR, authorities said. But the victim died at the scene, police said. Her identity was not immediately revealed.

Allen was later located in the area of 19th Avenue and Sloat Boulevard after someone called the police for a well-being check. There, the officers noticed that Allen matched the description of a "person of interest" in connection with the burglary and killing, police said.

Allen is now facing one count each of murder and first-degree residential burglary, prosecutors said. A special circumstance allegation was added to the murder charge, with prosecutors saying that the murder was committed during a first-degree burglary.
