Supt. Frank Bergen said the victims were a man and woman in their 20s and 30s. He said three other people were hospitalized with various injuries.

Police believe there could be more victims at other locations and urged citizens to contact authorities.

It wasn't immediately clear if police had any suspects or made arrests, or what led to the shooting.

The Canadian artist is currently in a highly publicized war of words with Philadelphia rapper Meek Mill, who initially claimed Drake did not write his own music.
