According to the Associated Press, Charice's father, Ricky Pempengco, was in a grocery store in San Pedro township on Monday when he "brushed against" a drunk man. Angered, the man pulled out an ice pick and stabbed Charice's father in the chest and back, says Laguna province police chief, Senior Supt. Gilbert Cruz.
The suspect has not been apprehended, but there is a cash award for any information leading to his arrest. The incident appears to be a random act of violence.
Charice's mother left the singer's father when the pop star was a young girl. However, Charice tweeted that she had a "really great relationship" with her dad before the separation. "I loved him and I will still love him," she wrote. "He's still my Dad after all."
