The mother of a 2-year-old girl whose body washed up in a trash bag on a Boston beach pleaded guilty to helping dispose of the toddler’s body Friday, according to reports.

Rachelle Bond, 42, admitted to helping her ex-boyfriend dump her dead daughter — dubbed “Baby Doe”— and covering up her death two years ago, CBS Boston reported.

She is expected to walk free after admitting to being an accessory after the fact in the 2015 killing of Bella Bond, according to The Boston Globe.

Bond will likely face just two years probation because she plans to testify against her former beau, Michael McCarthy, prosecutors said.

McCarthy is facing first-degree murder charges in the toddler’s death. He has denied killing her.

Bond will be tried separately, her lawyer Janice Bassil told The Globe.
