My name is [cms/tg/pid], I work for the Navajo Nation Department of Resource Enforcement, operating title Ranger. I am a Lieutenant and have been employed in law enforcement for 28 years. I have a background as a criminal investigator. One of the Rangers reported that a Navajo elderly couple and a girl saw a UFO land near their house in a rural area North-East of Chinle Arizona. According to the ranger, occupants went up to the residence and used what looked like flashlights to look around the house and the outhouse before leaving. Reports of flattened grass area where craft landed. Our intent is to interview in detail the family next week at earliest oppertunity as soon as ranger makes contact and sets up time. Interest in ground effects and any impressions. Have downloaded MUFON forms to facilitate our interview. Unknown exact date when event occured and how much ground evidence remains. Possibly two weeks since. Call me on cell number if any additional advice if you can.
