Kyzr Willis Mourned, Buried Thursday

BOSTON, MA — Mourning family laid a little boy to rest Thursday, grieving an accidental death that's been called a "citywide tragedy."

Boston Police last week determined 7-year-old Kyzr Willis' death at South Boston city summer program was a drowning, an "unfortunate, tragic accident" with no foul play suspected.

News of his death emerged last week on Tuesday night. According to police, Willis' mother, Melissa, dropped him at the Curley Community Center-run summer program in the morning. That afternoon, after the kids emerged from a swim on Carson Beach, police believe the boy went back into the water unattended and drowned. His body was found after a mass search along the shoreline, through the surrounding neighborhood, and in the water.

His funeral was held Thursday in Mattapan, where a horse-drawn hearse carried his casket.

Mayor Marty Walsh was reportedly in attendance.

The mayor, who moved quickly to introduce new safety standards across the city's summer programs, called the death a "terrible tragedy" last week.

"It's my hope and expectation as mayor that no family ever has to go through this type of loss. This is a tough day," he said, speaking the day after Willis was found. "It's very difficult to put in words."
