A shooting that killed three first responders Sunday in Burnsville happened after authorities responded to a reported sexual assault, court documents and a 911 transcript reveal.

A search warrant filed on Wednesday also indicated that a SWAT team, using a drone, found the suspect, Shannon Gooden, dead from a self-inflicted gunshot wound in a bedroom.

Burnsville officers Paul Elmstrand and Matthew Ruge and firefighter/paramedic Adam Finseth were killed when Gooden retreated, barricaded himself in a bedroom and began firing at officers, according to the warrant. A fourth responder, Sgt. Adam Medlicott, was hospitalized. City officials said he was released from the hospital on Monday and is recovering at home.

The warrant noted that Gooden is believed to have “used multiple different guns” and refused to cooperate with officers who tried to negotiate his peaceful surrender.

5 EYEWITNESS NEWS also obtained a 911 transcript on Wednesday of the first call that came into dispatch from inside the Burnsville home at 1:50 a.m. on Sunday. 

In it, the caller asked for police and provided an address. A small section of the remaining, brief conversation was redacted, but it showed that the caller references “my husband,” along with the words “Help me.” The transcript also noted there was screaming. Then, the call was disconnected. Dispatchers called back at least four times, according to the transcript, but could not keep anyone on the line.

Those calls all took place in about a five-minute span.

Investigators reported seven kids were inside the home with Gooden at the time but none of them were hurt.

The mother of three of Gooden’s kids told 5 EYEWITNESS NEWS that she feels “all of this could’ve been avoided,” and court records note that two orders for protection had previously been filed against Gooden, alleging that he was physically and emotionally abusive toward his kids’ mothers. However, both were ultimately dismissed.
