A crowdfunding site has been established for a man whose Greenwood Village home was “totaled” in an 18-hour SWAT standoff with a suspect authorities say was holed up with guns and a stockpile of drugs.

Leo Lech, the homeowner, says the campaign was started on his behalf by Fund Me America, which is “designed to provide financial and moral support for those on the front lines of conservative and libertarian causes.”

“They systematically blew up the house to extract one guy with a handgun,” Lech said early Monday. “They totaled the house. The insurance company says the house is a total complete loss. We’re going to have to bulldoze it to the ground.”

Lech said the campaign is to help his son, who was living in the home, pay for his family’s personal belongings destroyed in the June 3-4 standoff. While insurance is paying for the rebuilding, the property inside was not covered.

“There’s no specific amount,” Lech said of the campaign. “It’s just anything folks want.”

Lech said his family has declined $5,000 in temporary housing funds offered to them by the city of Greenwood Village. He said that money would only help his son pay for a fraction of the housing needed before a home is rebuilt at 4219 S. Alton St.

“The right ethical thing was to pay for a furnished apartment in that area until the house is rebuilt,” he said.

The standoff suspect, Robert Jonathan Seacat, 33, is being held on suspicion of a laundry list of charges that include attempted first-degree murder, burglary, assault on a peace officer and drug offenses.

Police say Seacat held police at bay by firing at officers and ignoring their commands. When he was arrested, Seacat was in possession of two loaded handguns, a shotgun and a backpack stuffed with baggies of methamphetamine, heroin and other drugs, according to an arrest warrant.

The incident started when an Aurora police officer attempted to lead Seacat into an office at a Walmart, where he was suspected of shoplifting. But Seacat ran to a Lexus in the parking lot, jumped in and fled.
