COLUMBIA HEIGHTS, Minn. — Authorities are searching for a man who hasn’t been in contact with his family in six months and is considered endangered. 

According to the Columbia Heights Police Department, 62-year-old David Alan Klint, was last known to be staying in a facility in the Twin Cities area. 

He isn’t known to have a car or phone, and officials say his family is concerned for his welfare as he has no similar history. 

Klint is described as 5’6, 150 pounds, with brown hair and hazel eyes. 

Anyone with information on his whereabouts is encouraged to contact police at (763) 427-1212 and reference case number 24236092. 

MINNEAPOLIS — Minnesota researchers are on the cutting edge of the fight against climate change.

The Natural Resources Research Institute (NRRI) and the city of Minneapolis are using Biochar to clean up pollution from different angles.

“It’s a way to remove carbon from the atmosphere,” explains NRRI researcher Eric Singsaas.

Singsaas and his research team in Duluth are creating this black carbon product by collecting wood damaged by storms and invasive species like the Emerald Ash Borer. Then, they incinerate it in an oxygen-free environment.

The result: small black bricks that look like charcoal, but prevent a more harmful substance from being released into air.

“If you just take a piece of wood and it falls on the ground, it will naturally decay and turn back into carbon dioxide,” Singsaas said. “If you take a piece of wood and you convert it in this process of pyrolysis, into Biochar, it’s a stable form of carbon.

“It sequesters that carbon away from the atmosphere,” Singsaas said.

Once biochar is made, NRRI researchers are putting it to use against an ever-growing list of threats to the climate.

“Biochar is one potential material that can be useful for filtering contaminants from stormwater,” NRRI researcher Bridget Ulrich said.

Ulrich’s biochar work focuses on filtering E. coli bacteria out of water sources and streams before they reach Minnesota’s lakes and rivers. ”But we’re also interested in organic contaminants like pesticides and PFAS, so biochar can also act as an adsorbent for those contaminants as well,” Ulrich said.

NRRI is also experimenting with mixing biochar and concrete, attempting to make the construction material more environmentally friendly.

“It improves things like the setting time of the concrete,” Singsaas said.

On the Iron Range, Singsaas believes the steel industry could one day swap coal for biochar in carrying out the forging process. “Coal is responsible for a lot of carbon emissions from those industries,” Singsaas shared.

“The Swiss Army knife of climate tools,” said Jim Doten, Carbon Sequestration Program Manager for the city of Minneapolis while explaining the allure of Biochar.

Standing in a green cit plot known as Ventura Village,  Doten explained to KARE 11’s Audrey Russo how biochar transformed an eyesore vacant lot into a flourishing community garden.

“We mix it with compost and it makes both of them work better. It’s the synergy,” Doten said. “It really helps hold the water, it helps with the drought resistance.”

Doten is no Johnny Come Lately to the promise of Biochar – He’s studied the science since 2012. With help from a $400,000 federal grant, he’ll take what he’s learned and scale it up near the University of Minnesota campus.

“What we’re doing there is we’re building a facility that will turn woodchips into biochar,” Doten told Russo.

The goal is to complete the facility by the end of the year, with biochar production beginning in early 2025. It’s a timeline that puts Minnesota ahead of the curve. “Right now, no city has this type of operation,” Doten said. “It’s a great place to be a leader and an innovator.”

Once the facility is complete, Doten says the biochar it produces will be used in Minneapolis and across the entire state.

“To help other governments around the area achieve their climate plans, their climate goals,” Doten said. “Restoration is what I see.”

“It’s not the answer, but it’s part of the answer. It’s a tool in a tool belt,“ he concluded. 

WILLMAR, Minn. — A Minneapolis man is charged with second-degree murder and multiple other felonies following a multi-county shooting spree Tuesday that left a New London man dead. 

Court documents filed in Kandiyohi County Thursday break down the charges against 25-year-old Ameer Musa Matariyeh, which also include attempted murder, first-degree assault and fleeing police. 

Prosecutors say the crime spree began in Minneapolis around 12:30 p.m. that day when Matariyeh fired several rounds from the top floor of an Uptown apartment building at his estranged girlfriend and her new partner. It would continue through several counties as the defendant was pursued west at high speed by Minneapolis police, eventually entering Kandiyohi County.  

The criminal complaint filed against Matariyeh says Kandiyohi County law enforcement was informed shortly after 1:50 p.m. that a man was headed their way in a stolen vehicle on Highway 7, being followed by members of a multi-county drug task force. 

Shortly after 2 p.m., a 911 call came in from a Kandiyohi County farmstead in Lake Lillian reporting that a man had been shot in the chest. The wife of the victim, 25-year-old Peter Mayerchak, told investigators he was out doing some work in the shed when she heard a pop, then looked out the window and saw her husband and another man yelling at each other. Mayerchak then ran into the house and she saw he had been shot. 

Investigators later discovered multiple bullet holes in the home’s windows and walls. 

Prosecutors say Matariyeh continued to flee west on Highway 7, and then on a county road at speeds reaching up to 130 mph. Eventually, law enforcement said, the defendant looped back to State Highway 23 and headed towards Willmar. Local law enforcement was informed that a Minneapolis PD crisis negotiator was on the phone with Natariyeh and that he was threatening to commit suicide by cop.  Multiple squads, including one driven by Kandiyohi County Sheriff Eric Tollefson, were pursuing the suspect’s vehicle. 

At 2:25 p.m., court documents say, law enforcement had OnStar disable the engine of the stolen car Natariyeh was driving, and one officer saw the suspect vehicle rear-end a green pickup near the Highway 7/23 bypass. That same officer said he saw Natariyeh jump out of the stolen Chevy, open the driver’s side door of the green pickup, and then noted that the defendant’s arm pointed and recoiled as if he fired a shot before running into traffic. 

The criminal complaint says at that point, Sheriff Tollefson and another officer ran up to the pickup and discovered that the driver, identified as 55-year-old Jerome Skluzacek of New London, had been shot in the head. Responding officers attempted life-saving measures but Skluzacek was declared dead on the scene. 

Multiple officers eventually caught up with Natariyeh, who raised his hands above his head and was taken into custody without incident. The firearms he allegedly used in the shootings were recovered near the highway median. While in the back seat of a squad car, Natariyeh reportedly said he wanted to die, and that he threw his life away because his girl had cheated on him. 

Additional charges could be filed against Natariyeh in Hennepin County in connection with the shooting incident in Minneapolis.
