Jurors in the Bella Bond murder trial finished their first full day of deliberations without reaching a verdict on Wednesday.
Michael McCarthy is accused of killing the daughter of his ex-girlfriend Rachelle Bond in 2015.
The jury deliberated for about two hours on Tuesday without reaching a verdict before being dismissed for the day. They reconvened around 9:20 a.m. Wednesday but were excused for the day at 4 p.m. without reaching a verdict.
Deliberations are expected to continue on Thursday morning. Jurors could convict McCarthy of first or second degree murder, or a lesser charge of involuntary manslaughter.
McCarthy's lawyer told jurors during closing arguments Tuesday that the girl's mother is the real killer and created a "web of lies" to blame him.
A prosecutor conceded Rachelle Bond behaved badly, but said there's no evidence she killed her daughter.
The little girl's body washed ashore on Deer Island in Winthrop, Massachusetts in July of 2015. A composite image of the girl was shared by millions of people on social media after she was dubbed "Baby Doe" by authorities trying to determine her identity.
