Two more suspects are now in custody in connection with an armed robbery that erupted into gunfire at a Riverview office park last November, after a Facebook Marketplace deal for shoes and a watch turned into an ambush. Michael Moore, 22, and Daniel Yanacheck, 21, were arrested on warrants tied to the robbery at the Bell Creek Professional Park complex, where investigators say two armed men confronted the seller at gunpoint and opened fire as he ran for safety.
According to Tampa Bay 28, the victim had arranged to sell the items through Facebook Marketplace when he was robbed at gunpoint at the Riverview complex. Investigators say one of the suspects carried a pistol while the other brandished a rifle, and shots were fired as the victim fled the scene. The seller was not injured, the outlet reported, citing the Hillsborough County Sheriff's Office.
Detectives secured arrest warrants for both Moore and Yanacheck as the investigation progressed, and Yanacheck was ultimately located hiding in an attic in Bradenton before deputies took him into custody, the station's report notes. Investigators also recovered one firearm believed to have been used during the robbery, per the same account.
A Third Suspect Already Behind Bars
The case already included a third man tied to setting up the deal. Syrus Pentecost, identified by HCSO as a 20-year-old who helped arrange the robbery, is serving a prison sentence, according to the station's report. Public booking records reviewed by Arrests.org show Pentecost received a 24-month Florida Department of Corrections sentence in September after being convicted on robbery with a firearm charges in Hillsborough County.
The Bell Creek Professional Park, where the robbery unfolded, is a commercial office park along White Viburnum Way and Mathog Road in Riverview, home to a mix of medical and professional suites off major commercial roadways, according to Bokors Corner.
Legal Exposure Under Florida's 10-20-Life Law
Moore and Yanacheck now face significant legal exposure. Under Florida Statute § 812.13 and § 775.087, armed robbery with a firearm is a first-degree felony punishable by up to life in prison, and Florida's 10-20-Life statute imposes a mandatory minimum of 10 years for possessing a firearm during a robbery, rising to 20 years if the firearm is discharged, according to FindLaw. Because investigators say shots were fired as the victim fled, that 20-year mandatory minimum threshold could come into play if the pair are convicted.
A Pattern Sheriff's Office Has Flagged Before
This is not the first time Hillsborough County's top lawman has sounded the alarm about online marketplace meetups turning violent. In March, Sheriff Chad Chronister issued a public service announcement warning residents about a rise in armed robberies tied to in-person meetups arranged through platforms like Facebook Marketplace, urging buyers and sellers to avoid meeting in private or unmonitored locations, per the Hillsborough County Sheriff's Office.
That warning lines up with state law. Under Florida House Bill 385, known as the Cassie Carli Law, which took effect in July 2024, all Florida sheriff's offices are required to designate at least one marked safe exchange zone with 24-hour video surveillance in their parking lots, according to WTSP. In Hillsborough County, every district patrol station, including District 1 on North 20th Street and District 2 on North Falkenburg Road, hosts a designated safe exchange zone with signage and continuous monitoring, according to SafeTrade Stations records.
In the wake of the Riverview arrests, the sheriff's office reminded residents to use those designated safe-exchange areas for online sales transactions, and recommended conducting deals during daylight hours and with other people nearby. The advice echoes a broader national pattern: federal prosecutions in 2026 have highlighted criminals publishing fake Marketplace listings to lure buyers and sellers into armed ambushes and forced ATM withdrawals, as Hoodline previously reported.
Part of a Broader Crime Trend in the County
The Riverview case adds to a string of recent Hillsborough County investigations involving online sales platforms. In September, HCSO detectives arrested a 49-year-old man accused of stealing thousands of dollars in commercial property and reselling it on Facebook Marketplace, according to Cape Coral / Sunshine News. That arrest came even as overall numbers have been trending downward: firearm-related violent crime in Hillsborough County declined 10.55% and overall violent crime dropped 13.85% in 2025 compared to 2024, according to sheriff's office figures reported by Hoodline.
