The community over the past few days has held vigils and marches, demanding justice for the 1-year-old. The Sergeant Benevolent Association also is offering $16,000 for an arrest from this incident.

Police say 25-year-old DeShawn Austin has been charged for murder and criminal possession of a weapon, in relation to an incident dating back to March in front of 566 Nostrand Ave. Media reports say he is the man who was brought into police custody for questioning Thursday in relation to Sunday night’s shooting.

Police Commissioner Dermot Shea says it’s the NYPD's mission to bring those responsible in recent shootings to justice.

"I can tell you just since Monday we have had 13 arrests in shootings, just like this week. Now these incidents didn't occur this week, 13 arrests as recently as last night," says Commissioner Shea.

No arrests have been made at this time in relation to the toddler’s death.
