Things get personal for 15th precinct skipper Tony Rodriguez (Esai Morales), who, while investigating a drug-related murder, comes across the body of his ex-wife, Angela. In another development, a social worker who assigned a baby to an unfit mother may be prosecuted for second-degree murder by Connie (Charlotte Ross) when the infant is scalded to death. And John Clark Jr. (Mark-Paul Gosselaar) is in for a not-unpleasant surprise when he is ordered to attend a training session. ~ Hal Erickson, Rovi
