Novi police waited five years for the phone call they got from the U.S. State Department in India this week.
The man wanted for murdering his wife and two children had been arrested.
Lakshminivasa Rao Nerusu, 46, had been a fugitive ever since police found the bodies of his 37-year-old wife, Jayalakshmi, their 14-year-old daughter, Tijasvi, and 12-year-old son, Siva. All three had been stabbed to death.
Police believe the three were killed inside he family's Novi home Oct. 13, 2008, but were not discovered until two weeks later. Police went to the home after reports that the children had not been attending school.
Lakshminivasa Nerusu left Detroit Metropolitan Airport on a one-way ticket to India one day after the killings.
Novi police chief David Molloy said the case has been a priority for his department.
"We've been in contact with them on a weekly basis and we have never relented in our pursuit of finding him. Obviously because of the brutal nature of the way these people were killed, it has been very important for us from day one that he is held accountable and is brought to justice," Molloy said.
Authorities in India are reportedly working closely with the FBI to have Lakshminivasa Nerusu brought back to the United States to face murder charges.
