Who is Paul Edward Mart?

Mart was arrested after an hours-long standoff that led to an evacuation by the authorities and according to a news release from the Otter Tail County Sheriff’s Office in Minnesota, multiple police agencies responded to the situation including a SWAT team.

The Sheriff’s Office received a call from someone who informed them about a woman who is dead at a home in Big Pine Lake. The alleged killer made several comments that "he remembered getting into a fight," adding "he slammed her head into the granite flooring a few times," "he cannot forgive himself," and "probably killed her," as per the criminal complaint.

Mart threatened to shoot at police if they arrived

Mart who sounded drunk had three guns and allegedly threatened to aim the weapons at police if they arrived. He also said, "they will have to kill him." The suspect surrendered after authorities brought in a negotiator. Investigators found a gun in a trash can.

Chris Cadem, a lawyer for Mart said that the death was an accident and noted that there is no evidence at present to tie his client to the weapon from which his wife suffered the gunshot wound. "Based again on the information we’ve uncovered in the last 48 hours, we are confident that gunshot residue is going to come back on the hands of the decedent," Cadem said.

"We are very confident that my client will be able to demonstrate this was, in fact, an accident, that this did not happen by any action or deliberate act by my client, and that he will be exonerated of this charge," he added.

Michelle Eldien, Otter Tail County Attorney filed one count of murder in the second degree against Mart. "The charge is an intentional murder based on the evidence that was collected and known when the complaint was filed," said Eldien.
