Prosecutors on Wednesday rested their case against Noah Anthony Charles King.

Judge Mark Munger is expected to hear closing arguments on Thursday before issuing his verdict.

The state's two final witnesses were investigators, who provided an outline of the Duluth Police Department's investigation into the death of William Grahek.

At several points, their testimony and other evidence directly contradicted King's alibi statements and the claims of co-defendant Noah Duane Baker, who on Tuesday asserted that he alone was responsible for Grahek's death.

King's account disputed

It took several weeks for police to make any arrests in the case. But it was just minutes into the investigation that they arrived at King's door.

Several police officials have testified that a K-9 followed a track from Grahek's home directly across an alley to King's residence, 513 E. 10th St. Additionally, investigators said footprints discovered between the two residences matched a pair of sneakers recovered from King's house.

In a recorded interview played in court Tuesday, King claimed that he arrived home from a meeting with his probation officer in the late morning and stayed there, watching TV with his girlfriend and stepmother, until walking across the street to a gas station later in the afternoon.

But former Duluth police investigator Jeff Keast, who spent Wednesday morning on the witness stand, punched holes in that account.

Keast testified that he learned from King's girlfriend that Noah Baker and Deandre Demetrius Davenport arrived at the residence that afternoon. She reportedly stated that all three men went into King's bedroom for about 15 minutes, emerging in all-black clothing.

Keast said the girlfriend stated that the three left, with King later returning alone and wearing different clothing. She added that King directed her to delete calls he allegedly made from her phone and, if confronted by police, to claim that he was home watching TV the entire time, according to Keast.

The court also heard about a wrench allegedly carried by King during the attempted robbery of Grahek.

Noah Baker, before recanting his story Tuesday, had testified that King carried the wrench in case they needed to subdue Grahek's dog. Keast testified that a large crescent wrench was found on the passenger-side floorboard of Tara Rai Baker's vehicle, which allegedly was used in the commission of the crime.

Keast said no other tools were found in Baker's Jeep or residence, but other wrenches similar in appearance were located at King's house.

Video shows timeline

Prosecutors closed their case with investigator Mike Tinsley, who produced a video stitching together surveillance footage from a number of Twin Ports businesses over the period of Feb. 14-15.

Tinsley testified that Tara Baker's white Jeep could be seen heading toward the crime scene just before 1:30 p.m. Noah Baker and Deandre Davenport also could be seen walking in the area, he said.

Grahek was shot just before 2 p.m. Tinsley said video shows the Jeep fleeing at a high rate of speed a few blocks away at 1:59 p.m.

Images showed the Jeep pulling in to the Cenex station directly across the street from King's house at 2:20 p.m. Tinsley said King is seen getting out, wearing a white T-shirt and blue jeans, as Tara Baker enters the store.

After apparently retrieving Davenport and Tara Baker's two young children, the alleged shooter and the two siblings went to the Signature Inn in Superior's Billings Park neighborhood later that night, Tinsley said.

The next day, he said, co-defendant Xavier Alfred Haywood, who allegedly planned the attempted robbery and arranged for the room, is seen at the hotel. It was during this time, Tinsley said, that the two men went to the Morgan Park neighborhood to burn clothing.

Around the same time, the investigator said, a man with connections to Davenport was seen at the hotel. Police said the alleged murder weapon was later recovered from his Austin, Minn., residence.

Defense attorney Steve Bergeson did not indicate if he planned to introduce any evidence.

About the case

Noah Anthony Charles King is standing trial in State District Court in Duluth in connection with William Grahek's death. One of five defendants to face charges, he is the first to go to trial.

King, 20, is accused of accompanying two other men during an attempted robbery of drugs and cash from Grahek's East Hillside residence, 510 E. 11th St., on Feb. 14, 2017. Grahek, 22, was shot twice, allegedly Deandre Demetrius Davenport, after he refused to comply with their demands.

Prosecutors have alleged that King, Davenport and Noah Duane Baker went to the residence based on information provided by co-defendant Xavier Alfred Haywood. Defense attorneys have framed Grahek's death as an unintentional act.

King is charged with two counts of first-degree murder and one count each of intentional second-degree murder and attempted first-degree aggravated robbery. If convicted on either murder charge, he would face a mandatory life sentence with potential for parole only after 30 years.

King waived his right to a jury, so the case is being heard by 6th Judicial District Judge Mark Munger, who will have up to a week after hearing closing arguments to issue a verdict.
