Several neighbors were standing out in the cold Monday night after a police standoff in the 6600 block of west 15th Place in Sioux Falls left one man dead.
Here's what police are telling us.
He was a 22-year-old man but they're not releasing his name yet.
And he was alone at the time of the shooting.
Police say it was just before five o'clock when they were called to the mobile home court and learned a man had been firing a gun both inside and outside his home.
An ambulance leaves the scene with the victim inside.
The standoff had a few neighbors on edge.
Police say they tried talking to the man, but he responded with gunfire.
They say a couple of shots were fired at the man outside his home where he was shot and killed.
One woman says she saw one of her neighbors, standing outside his home firing straight into the air before police warned her to get back inside.
Neighbor Deb Aldrich said "I was standing out here watching, and all of a sudden a gun shot straight up into the air."
Neighbor Kevin Martin said "we were inside, and we hear these three rifle reports, like a 'kack, kack, kack,' so we all kind of hit the deck, because we don't want to get hit by a stray bullet or something because we weren't' sure what was going on."
"He seemed like a nice guy, I mean he used to talk to me all the time, when he'd come up and get his mail, that's what's weird. I mean I don't understand it," Aldrich said.
"There was some kind of a wand that they had hooked up, don't know if it was to a vehicle, or something but it looked like they used it as a battering ram, and hit the door and the door went flying open, and we saw a few officers go in," Martin said.
Sioux Falls Police, along with the Minnehaha County Sheriff and SWAT team handled the standoff.
DCI will be handling the investigation while the officer who fired the shots will be placed on leave.
