‘Awkward positioning’: 81-year-old mom found brutally stuffed in pullout couch face-first after being left there and ignored for hours by her daughters until she died, police say

A disturbing elder neglect case in California has resulted in two sisters being charged with murder after authorities say their 81-year-old mother was left trapped in a dangerous position for hours and ultimately died from suffocation.

According to investigators, 81-year-old Kun-Ying Yang was found unresponsive inside her San Diego apartment on March 6, 2026. What initially appeared to be a medical emergency soon evolved into a homicide investigation after authorities uncovered the circumstances surrounding her death.

The case has drawn widespread attention because of allegations that Yang’s daughters failed to provide aid or seek medical assistance while their mother remained trapped in a position that ultimately proved fatal.

Emergency Call and Grim Scene

Family Members Call 911

Shortly before midnight on March 6, San Diego emergency dispatchers received a 911 call from family members reporting that Yang had been found unresponsive at an apartment located on the 6300 block of Genesee Avenue in the University City area of San Diego.

Police officers and firefighters responded to the residence and attempted life-saving measures after finding the elderly woman unconscious. Despite their efforts, Yang was pronounced dead at the scene.

Woman Found Face-Down in Pullout Couch

Although early police statements described Yang as being “positioned awkwardly on a bed,” investigators later revealed far more disturbing details.

According to San Diego Police Lt. Christopher Leahy, Yang was actually found face-down in a gap between a pullout couch and the bed frame. Authorities believe she had remained trapped in that position for at least 15 hours before she was discovered.

Investigators said they could not determine exactly how Yang became wedged in the space, but they emphasized that she should never have remained there for such an extended period without intervention.

Autopsy Reveals Cause of Death

Positional Asphyxia Determined to Be Fatal

A medical examination later determined that Yang died from positional asphyxia, a condition in which a person’s body position prevents normal breathing and causes suffocation. Investigators said neglect was identified as a contributing factor in her death.

Because of those findings, the medical examiner ruled Yang’s death a homicide.

Police Question Lack of Assistance

Lt. Leahy publicly expressed concern about the circumstances surrounding Yang’s death.

According to investigators, Yang remained in the dangerous position for many hours, yet no meaningful efforts were made to remove her from the gap or obtain appropriate medical treatment. Authorities said that regardless of how she became trapped, she should have received immediate assistance.

Investigation Focuses on Daughters

Caregiving Responsibilities Under Scrutiny

As detectives continued investigating the death, they discovered that Yang and her elderly husband were dependent on their daughters for care because they were unable to adequately care for themselves.

Investigators working alongside Adult Protective Services examined the living conditions and caregiving arrangements within the home. Their findings ultimately shifted the investigation toward potential criminal neglect.

Previous Complaints Reportedly Existed

Authorities stated that there had been prior complaints concerning the quality of care being provided to the elderly parents. Investigators reviewed those concerns as part of the broader inquiry into Yang’s death and the welfare of the family.

Police alleged that the sisters endangered their parents’ health and failed to fulfill their legal responsibilities as caregivers.

Additional Concerns Involving Elderly Father

Neglect Allegations Extend Beyond Mother’s Death

During the investigation, authorities also examined the condition and care of Yang’s 88-year-old husband.

Police alleged that the sisters neglected their father as well. The elder abuse charges filed against the women are reportedly connected to concerns regarding the father’s care and welfare.

Investigators said the evidence suggested a broader pattern of neglect affecting both elderly parents.

Arrests and Criminal Charges

Sisters Taken Into Custody

On June 4, 2026, nearly three months after Yang’s death, police arrested her daughters, 52-year-old Ingrid Wu and 53-year-old Rebecca Wu.

The women were booked into the Las Colinas Women’s Detention Facility in Santee, California.

Facing First-Degree Murder and Elder Abuse Charges

Court and jail records show that both sisters were charged with first-degree murder in connection with their mother’s death. They also face felony elder abuse charges related to the alleged neglect uncovered during the investigation.

Authorities have indicated that the elder abuse allegations specifically involve the treatment and care of the couple’s 88-year-old father.

Held Without Bail

Court Proceedings Begin

Following their arrests, Ingrid Wu and Rebecca Wu were ordered held without bail while criminal proceedings moved forward. Jail records indicated they were not eligible for release pending further court action.

The case is expected to proceed through the California court system as prosecutors seek to prove that the sisters’ alleged neglect directly contributed to their mother’s death.

A Case That Raises Questions About Elder Care

The death of Kun-Ying Yang has become a stark example of the dangers of elder neglect. Investigators allege that an elderly woman remained trapped face-down between a pullout couch and bed frame for at least 15 hours without receiving necessary assistance, ultimately dying from positional asphyxia.

Prosecutors now contend that the failure to provide care and seek medical help transformed what may have begun as a tragic accident into a criminal case. With murder and elder abuse charges filed against both daughters, the legal proceedings will determine whether they bear criminal responsibility for the death of their mother and the alleged neglect of their elderly father.
