A woman and two children found slain in their Novi, Mich., home were killed two weeks before police discovered their bodies, according to federal court records.

Unemployed Indian-American computer programmer Lakshminivasa Rao Nerusu on Oct. 13 killed his wife, Jayalakshmi Nerusu, 37, and their 14-year-old daughter Tejasvi Nerusu and 12-year-old son Siva Kumar Nerusu, authorities said.

The 42-year-old has been charged with three counts of first-degree murder.
