Gallup Police Department officers investigated a shooting April 13 at Cliffside III Apartments at 601 Dani Dr.

Captain Erin Toadlena Pablo told the Gallup Sun, a 71-year-old man identified as Herbert Jefferson, Sr., shot two of his relatives, one of them a minor, then fled the scene for Fort Defiance, Ariz., where he is believed to have shot himself.

His 34-year-old daughter-in-law, Fran Tah, was killed, as was her daughter.

The Navajo Nation Police Department, Window Rock District, secured and processed that crime scene where they recovered the firearm believed to have been used at the Cliffside Apartments.

NPD investigators also assisted by locating and interviewing witnesses.

Through interviews, detectives learned that Jefferson Sr. had allegedly abused the juvenile female.

This remains an ongoing investigation.
