Yazenia Marie Diaz/David Isaiah Gibson/Loveless Daniel Naylor - Laramie County Sheriff's Office

Three people are facing felony drug charges after a Cheyenne-area trooper found nearly two pounds of heroin in their car.

According to an affidavit, 40-year-old Loveless Daniel Naylor, of South Bend, Indiana, was pulled over for doing 88 mph in a 75 mph zone near Roundtop Road on Feb. 15.

The traffic stop revealed Naylor was driving on a suspended license.

While identifying Naylor's passengers -- 38-year-old Yazenia Marie Diaz, of Mishawaka, Indiana, and 46-year-old David Isaiah Gibson, of Chicago, Illinois -- the trooper detected "a strong odor of raw marijuana coming from within the trunk."

The trooper searched the car and found misdemeanor amounts of suspected marijuana and 872.9 grams of heroin. A loaded Beretta 9mm pistol was also located "behind the carpet" in the trunk.

Interviews revealed both Diaz and Gibson had left Chicago, Illinois to pick up Naylor in Las Vegas, Nevada. Gibson said he was paid $1,500 to pick up Naylor and that he knew Naylor to sell drugs in the South Bend, Indiana area.

It was also determined that the three have extensive criminal histories, including possession of controlled substances and murder.

All three have been charged with conspiracy to deliver heroin. Gibson and Naylor are also facing possession with intent to deliver heroin and felony possession of heroin charges.

Gibson and Naylor's bonds were set at $50,000 cash, while Diaz's was set at $5,000 cash. Their preliminary hearings are scheduled for Feb. 26 at 3 p.m.
