Minnehaha County Sheriff’s Office Details “Significant And Concerning” Explosives Case

Local News

We are learning more about the man at the center of a potentially explosive situation and a neighborhood evacuation on the east side of Sioux Falls. KELOLAND News was in the courtroom Thursday as the suspect made an appearance. 

43-year-old Mark Einerwold faces charges of burglary, intentional damage to property, and possession of a controlled weapon and explosives. The judge set his bond at $200,000.

The Minnehaha County Sheriff’s Office says investigators found a lot of explosives on Blaine Avenue Wednesday night.

“The amount of explosive materials and what was there is significant and concerning,” Minnehaha County Sheriff Mike Milstead said.

“We got lucky that something bad didn’t happen, and we weren’t on the back end of this, we got on the front end of it,” said Jason Gearman, Captain with the Minnehaha County Sheriff’s Office. 

That has a lot of neighbors talking. Jodie Cowman, who lives in the apartment above Einerwold, says she doesn’t really know anything about him.

“Not really,” Cowman said. “We had only talked to him a few times, just passing by, you know. We just formally met like last week I think. He was super nice, but apparently not.”

She’s surprised by the news.

“Yeah, absolutely,” Cowman said. “He didn’t, he doesn’t come off as the type, but it’s always the people you least suspect, right?”

Milstead says “a big tragedy” might have been averted.

“I think it was an example of how law enforcement can suddenly come across something totally unexpected and face a danger you never expected,” Milstead said. “This was a fairly simple warrant service, search warrant execution on a residence in Sioux Falls, and suddenly turned into, it could have been a really, really bad situation.”
