Jury Convicts KC Man of Illegal Firearms, Stalking

KANSAS CITY, Mo. – A Kansas City, Mo., man was convicted by a federal trial jury today of illegally possessing firearms, including purchasing firearms advertised on the internet, and of stalking two female victims associated with massage parlors in Kansas.

Robert J. Gross, 67, of Kansas City, was found guilty of two counts of stalking victims across state lines, three counts of being a felon in possession of a firearm, and three counts of receiving a firearm while under indictment.

Gross was under investigation in 2017 for destroying property and harassing and stalking women associated with massage parlors in Kansas, which led to him being placed under surveillance by law enforcement. While under surveillance in December 2017, Gross purchased handcuffs and other items from a surplus store, visited a gun show twice, and purchased two shotguns from a private seller advertising on the internet.

On Oct. 1, 2017, Gross visited two Olathe, Kan., massage parlors – A+ Health Massage and Alpha Massage – but was told to leave because he was asking for inappropriate sexual favors. He then went to Tea Spa Massage in Lawrence, Kan., where he paid for a massage. When Gross took all his clothes off, the masseuse told him she wouldn’t do anything sexual and he was told to leave the business. She called the manager, who also managed the other two businesses in Olathe. Video surveillance depicts Gross walking around the business completely naked, harassing and threatening the masseuse. The video also shows Gross grabbing and groping her. She left the store and flagged down a passing man for assistance in getting Gross out of the business. Gross then got dressed and left the business.

The manager told investigators that she saw Gross driving through the residential neighborhood where she lived on the same day.

Law enforcement investigators began surveillance of Gross after these incidents.

On Dec. 2, 2017, officers saw Gross purchase four sets of handcuffs, two black shirts with “SECURITY” written on them with badges on the front, and two balaclavas (a garment used to conceal facial identity) from a surplus store in Kansas City, Kan. The manager of the business told investigators that Gross had purchased two sets of handcuffs the week before.

On Dec. 16, 2017, officers saw Gross inquiring about the purchase of firearms at the Kansas City Gun Show located at the KCI Expo Center. Gross picked up and handled a 9mm Velocity “Uzi”-type firearm at one of the booths. The dealer at the booth told investigators that Gross, who approached his booth multiple times throughout the day, had asked about purchasing up to three firearms. The next day, Gross visited the gun show again and was seen inquiring about the purchase of firearms. Gross visited a different booth, where he picked up a Smith and Wesson 9mm handgun.

At that time, Gross was a convicted felon and also under indictment in the state of Kansas for aggravated sexual battery. Under federal law, it is illegal for anyone who has been convicted of a felony, or who is under indictment, to be in possession of any firearm or ammunition. Gross has prior felony convictions for possession with intent to distribute cocaine and making terroristic threats to a former girlfriend.

On Dec. 22, 2017, Gross returned to the surplus store in Kansas City, Kan., and was observed purchasing four more sets of handcuffs and a balaclava. Gross also asked about purchasing a bulletproof vest.

On Dec. 22, 2017, officers observed Gross purchase two shotguns from an individual in the parking lot of the Lowe’s Home Improvement store in Liberty, Mo. Gross first drove to the Pizza Ranch parking lot, where he removed the license plate from the front of his car. The rear license plate had been removed as well. Then Gross drove to the nearby Lowe’s store, where he was met by an individual driving a white pickup truck. The unidentified individual sold Gross two shotguns, which he handed to Gross from his truck. As Gross was putting two shotguns in the trunk of his car, officers arrested him for being a felon in possession of firearms.

The individual who sold the shotguns to Gross told investigators that Gross called him the day before, after seeing the Savage 12-gauge shotgun and Winchester 12-gauge shotgun advertised for sale on a website. Gross told him he wanted to buy the two shotguns for $350 and they arranged to meet at Lowe’s to conduct the sale.

Following the presentation of evidence, the jury in the U.S. District Court in Kansas City, Mo., deliberated for approximately two hours before returning the guilty verdict to U.S. District Judge Gary A. Fenner, ending a trial that began Monday, May 13, 2019.

Under federal statutes, Gross is subject to a sentence of up to 55 years in federal prison without parole. The maximum statutory sentence is prescribed by Congress and is provided here for informational purposes, as the sentencing of the defendant will be determined by the court based on the advisory sentencing guidelines and other statutory factors. A sentencing hearing will be scheduled after the completion of a presentence investigation by the United States Probation Office.

This case is being prosecuted by Assistant U.S. Attorneys Jess Michaelsen and Alison D. Dunning, with cooperation from the Platte County, Mo., Prosecutor’s Office. It was investigated by the FBI, the Independence, Mo., Police Department, the Kansas City, Mo., Police Department, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Olathe, Kan., Police Department, the Lawrence, Kan., Police Department, and the Douglas County, Mo., Sheriff’s Department.
