Julia Boomer was found inside the Throop Avenue apartment in Bedford-Stuyvesant shortly before 10 p.m. Tuesday, and rushed to Kings County Hospital where she was pronounced dead, police said.

Sources said Boomer’s 22-year-old grandson left the scene but returned later and was taken into custody for questioning by detectives from the NYPD’s 79th Precinct.

No charges have been filed in the incident.

Boomer and her grandson allegedly had a spat that turned violent, and had at least one prior domestic incident, the sources said.

The elderly woman was stabbed multiple times in the head and torso, the sources said.

Records show that her grandson, whose name is being withheld because he has not been charged, has two open criminal cases in Brooklyn, a harassment and petty larceny case from Oct. 27, 2025 and a grand larceny and assault case stemming from an incident on July 3.
