Rochester man faces cocaine possession, sale charges; warrants detail second search location, connection with crack production suspect

(ABC 6 News) – A Rochester man faces drug charges following a Monday evening search of his home.

The Olmsted County Sheriff’s Office and SE MN Violent Crime Enforcement Team served a knock-and-announce warrant for Dennis Siggers in the 3900 block of 18th Avenue NW at about 5 p.m. Feb. 26.

Lt. Malinda Hanson said Siggers was detained by deputies as he returned to the home, while a 40-year-old woman and two elementary-age children left the residence before law enforcement began their search.

Hanson said deputies found a brick of presumptive cocaine and referred charges of 1st-degree drug possession and drug sales.

Siggers was officially charged with 1st-degree drug sale and 1st-degree drug possession Wednesday, Feb. 28.

He is currently held at the Olmsted County ADC on $100,000 bond.

Siggers’ charging documents allege that Olmsted County law enforcement had tracked his phone earlier in the day, had noted him traveling to the Twin Cities, and took him into custody before he re-entered the home.

According to court documents, law enforcement found a “gift-style bag” in the passenger seat, containing a brick of “field positive” cocaine that weighed 1,032.1 grams.

During the search of the home, officers found six cell phones and $6,000 in U.S. currency, according to the court documents — which, together, were considered “indicative of controlled substance sales.”

Search warrants publicly filed Tuesday indicate that law enforcement suspected Siggers of drug sales after a probation officer told police he was working a part-time job while providing for a family; however, he had recently purchased a townhome, vehicle, and expensive clothes and accessories.

Siggers was previously convicted of 2nd-degree drug sale in 2019.

In January of 2024, law enforcement began electronically surveilling Siggers’ electronics, including his use of CashApp, with which he allegedly sent around $21,000 in less than two months, and received around $20,000.

Warrants indicated that law enforcement also watched Siggers make contact with several individuals with previous drug arrests and convictions on their records in the month of January.

Those individuals included Tyler Johnson, who was arrested two weeks ago after a warrant allegedly revealed evidence of crack cocaine production in his garage.

Siggers also traveled to the Metro area several times, and law enforcement noted that he made frequent stopped at a residence in the 1500 block of 10th Avenue SE.

Law enforcement posited that the 10th Avenue residence could be a “stash house” used to distance Siggers from his alleged drug supply, and filed warrants to search the home for controlled substances, books and records related to possible drug sales, and other evidence of possible drug sales.
