The break-in happened sometime on the night of July 17 in a residential area along Welsh Road, said township police.
The house was "heavily ransacked" by the time officers arrived, the department said. In addition to leaving a blood stain on the floor, authorities said the burglars took cash and "high-end jewelry."
Investigators have since issued warrants for two suspects in the case: Henry Castillo-Suarez, 47, and Cesar Almeida-Casas, 28, both of Queens, New York.
