Alleged key Witness in Las Vegas Massacre Kills Himself and Daughter After FBI Raid

At this time, it is unknown whether the information regarding John Beilman's connection to the Las Vegas mass shooting as a key witness is true or false. It is being provided for informational purposes only.

According to the website Neon Nettle, a key witness in the tragic Las Vegas mass shooting has killed himself and his disabled daughter following a raid by the FBI at his home.

The man's name is John Beilman and he was allegedly wanted for questioning in connection with a device discovered in Stephen Paddock's Mandalay Bay hotel room.

Neon Nettle reports sources close to the investigation revealed federal agents obtained a search warrant and raided Beilman's Fairport home the day before he killed his daughter and himself with a 12-gauge shotgun.

Nicole Beilman, John Beilman's 27-year old daughter, had a rare neurological disorder called Rett Syndrome. She depended on her parents for personal care.

According to a report on The Impious Digest, authorities discovered a suspicious cell phone charger in the Vegas shooter's hotel room at the Mandalay Bay. The charger was reported to have no accompanying phone, but technology experts identified that this type of charger is used to power a CP502520 3.0V 600mAh Li-MnO2 non-rechargeable thin cell battery, which is allegedly often times used in U.S. special forces and other covert government communication devices.

This unique lithium battery is produced by a New York based company, Ultralife Corporation, which specializes in military-grade communication systems for the Pentagon. Coincidentally, its lead development engineer was reported to be John Beilman.

On his LinkedIn profile, Beilman described himself as a "product design and manufacturing professional." He was employed at Ultralife Corporation between 2007-2012 where he reportedly worked on various top secret U.S. military projects. After he left the corporation, he became an engineer at the General Motors Research Facility in Rochester, New York.
