WICHITA FALLS, Texas (CBSDFW.COM) – The former Acting Police Chief of Olney, Texas was sentenced Monday to 10 years in federal prison for threatening a man at gunpoint.

Former Acting Chief Robert Michael Cross, 35, pleaded guilty last October to deprivation of rights under color of law following an investigation by the FBI’s Dallas Field Office.

“The city of Olney deserves police officers with respect for the rule of law,” said U.S. Attorney for the Northern District of Texas Erin Nealy Cox. “Instead, this defendant abused his power, stripping citizens of their dignity for his own perverse ends. We are gratified he has been held to account for his despicable behavior.”

“Law enforcement officers are responsible for upholding the law and protecting their communities from harm. The defendant used his position of authority to prey on vulnerable individuals and exploit them for his personal gain,” said FBI Dallas Special Agent in Charge Matthew J. DeSarno. “The FBI is committed to preserving trust in law enforcement. We will criminally pursue any officer that violates the law and abuses their oath to protect and serve.”

In plea papers and in other information provided in court, Cross admitted that shortly after arresting two individuals for aggravated robbery offenses, he coerced them into engaging in conduct for his own personal benefit, promising to have the criminal cases against them dismissed if they complied with his demands.

About a month after the arrest, on December 20, 2017, he took them out in his vehicle to eat dinner and catch a movie, according to the U.S. Attorney’s Office.

That evening, he brandished a pistol, threatening one victim with bodily injury and coercing the victim to engage in sex acts with another individual, thereby willfully depriving the victim of the Constitutional right to be free from unreasonable force by a law enforcement officer.

Olney is about 100 miles northwest of Fort Worth.
