An Oceanside grandmother was murdered in her home, and her daughter allegedly confesses to the crime.

Police say this stabbing death started over a conversation about medical care - not for the mom, but the daughter who suffers from mental illness.

56-year-old Suzan Grossman-Kerner is now in jail cell, facing murder charges in the death of her mother, 79-year-old Irma Grossman.

"If the allegations are true that she stabbed her mother, one can image there's a serious mental illness involved in this," said Todd Greenberg, Grossman-Kerner's attorney.

Police say the daughter,who suffered from mental illness, confessed that she stabbed her mother multiple times.

It happened after an argument Monday, in the middle of the day, in an Oceanside home in the 2700 block of Terrell Avenue.

Neighbors say they had no idea what was happening, just steps from their door. "It was a little scary and threatening that something in our quiet neighborhood ... to require all those cars."

According to court records, Grossman-Kerner called police after the stabbing, first telling them her mother was attacked.

After the 79-year-old was taken to the hospital,  she died from her injuries. Neighbors also tell PIX11 what makes this death even more shocking is that the mom and daughter were like best friends ... always together.

Grossman-Kerner is a mother of three and practiced law. Neighbors tell PIX11 the 79-year-old mother lost her husband just a few years ago.
