A homeless woman has pleaded guilty to two counts of murder in the fatal stabbings of an Ontario mother and daughter who were visiting Atlantic City.

The Press of Atlantic City reports 45-year-old Antoinette Pelzer entered her pleas Friday afternoon.

Authorities say Pelzer stabbed 80-year-old Po Lin Wan and 47-year-old Alice Mei See Leung to death during a robbery attempt in May 2012.
