Silent lighted craft flies over house, witness later discovers body marks.Ten days after seeing a brilliant white light change luminosity and mimic the planet Mercury in northern Colorado, I saw a second craft. I was driving home, southbound on US287 in Laramie, Wyoming, when I spotted an approaching flying object to the southeast. It was white with an orange tint and was still approaching when I reached home three miles south of town. I viewed the UFO through binoculars as it flew silently over the house at an estimated 1200 feet altitude and estimated speed of 100 mph. It appeared oblong in shape, but all I could really see were four or five bright lights of various colors, including a white strobe and dimmer red and green lights. The next morning I discovered a bleeding puncture wound on my right ear after showering. This report should be studied together with another sighting which took place two days later, in order to appreciate the emerging pattern. At the time of this event, I was 27 years old, a private pilot and college student.((NUFORC Note: Date may be approximate, although witness does not indicate that fact. One of three seemingly credible reports from same source. Please see report for Ft. Collins, WY, 01/07/89, and Laramie, WY, 01/18/89. PD))
