This week's story about a missing persons report that led to a welfare check that led to the discovery of dismembered human remains has an update from neighbors on the street. They say that loud fights and noises often came from the home on Del Monte Street in the Outer Mission.

As the neighbors tell KPIX/CBS SF, they have not seen 73-year-old Benedict Ching in a number of days. Ching was reported missing, and police arrived Monday morning to do a welfare check.

One neighbor, Mei Chen, recalled hearing "Bum! Bum!" sounds against the house's walls, and suggested it might have been a fight. The fights were reportedly a regular occurrence, though perhaps only as of recently.

Ching lived in the house for decades, as a neighbor tells the Chronicle, and a woman and child lived there with Ching at some point as well. Ching had been living by himself until a few months ago, when a family — a woman, a man and two children — began "frequenting" the property.

Little is known about what was found in the house, but the FBI is reportedly assisting in the investigation with the SFPD — perhaps because of the possibility of a serial killer, or just the depravity of the crime. As one SFist commenter noted Wednesday, the dismemberment aspect brings up both this disturbing recent case of a murder and dismemberment at a Mid-Market hotel in which two suspects remain in custody, and the body-stuffed-in-a-fishtank story from 2018, which remains unsolved. Though, what little we know so far points to there being no connection between these three murders.

Dismemberment is thought to be a particularly depraved and uncommon occurrence, even among hardened killers, as the Chron notes — though it's been disturbingly frequent in homicide stories in SF of the last couple of years. There was also the June 2018 case of 66-year-old Maggie Mamer who was discovered dead and dismembered and stuffed in a plastic storage tub during a welfare check by police. Mamer's roommate, 47-year-old Lisa Gonzales, was arrested and charged with the murder, but she has pleaded not guilty.

The remains on Del Monte Street have yet to be identified by the Medical Examiner's office, and neighbors who saw the Medical Examiner's employees removing remains from the house tell KPIX they believed there may have been two bodies removed.

Again, the investigation remains open, and anyone with possible information regarding the case is asked to call the SFPD Tip Line at 415-575-4444, or text a tip to TIP411 and begin the text message with SFPD. Tips can be made anonymously.
