Matthew R. Knowles, 31, and Harold E. Powell, 19, are each charged with third-degree burglary.

Knowles is also charged with first-degree theft and first-degree arson.

According to the criminal complaints, filed with the Webster County attorney’s office, Knowles and Powell broke into Fort Dodge Asphalt, 2125 Parker Drive, Sunday morning.

The complaint stated Knowles took a 2008 Ford F250, along with a homemade trailer. That trailer had a number of items on it, including a generator, tools, toolbox, heater and welding tanks.

Knowles, according to the complaint, later drove the truck underneath the Karl King Bridge on Second Avenue South, where he allegedly doused it in diesel fuel before setting it on fire and driving it into the Des Moines River.

The truck was later found and recovered by the Fort Dodge Police Department.

Investigators later found the trailer and missing items at a home near the intersection of 15th Street and 20th Avenue North, which is where Knowles and Powell were also found, according to the complaint.

Both men made their initial appearances in Webster County Magistrate Court Tuesday morning, where Magistrate William Habhab ordered both men held on cash bonds.

Knowles’ bond totaled $25,000, while Powell’s bond was $5,000.

Their preliminary hearings have been set for Jan. 3.
