An Illinois man was arrested by Lake Delton Police Sunday night after he stabbed and sliced his brother with a piece of broken glass at Wilderness Resort.

Kelvin Harmon, 25, of Bellwood, Ill., was charged with felony aggravated assault with a weapon and misdemeanor criminal damage to property and disorderly conduct after he attacked his brother, Lamarr Johnson, in their hotel room at Glacier Canyon Lodge at Wilderness Resort.

Johnson said the family was in the area to celebrate his grandparents’ 50th wedding anniversary, according to a police report.

He said things had been fine with Harmon until Sunday morning when the two got into a verbal argument. Johnson said he tried to talk Harmon into going to the waterpark, but Harmon declined.

Johnson told Harmon they were on vacation, and it was only common sense to have a good time. Johnson told police that this was when Harmon became upset, and started yelling about common sense.

Johnson left for the waterpark without Harmon. Later, the two were walking in the parking lot to Monk’s for dinner.

Johnson said he answered his phone, and Harmon became upset, throwing his cell phone in his face because he didn’t have one.

At dinner, Johnson said Harmon became intoxicated and started to “run his mouth.” So Johnson left.

After ordering his meal, Harmon followed his brother to the room and banged on the doors so Johnson would let him in. When the door opened, Harmon picked up a floor lamp and said, “Do you feel like dying today?” according to the police report.

Harmon threw the lamp, but Johnson was able to deflect it. Then, Harmon picked up a piece of the broken glass from the lamp.

Johnson said Harmon sliced and stabbed at him about 10 times, connecting at least three times. He sustained a cut to the right forearm, and slices to his left triceps and forearm.

He escaped and ran to the parking lot. He called his father, who was still at Monk’s, and his father told him to call the police.

Johnson was still bleeding when police arrived. EMS personnel bandaged his wounds, but he declined a ride to the hospital.

Johnson said he feared for his life and had never seen Harmon act like this before. He said he believed Harmon wanted to kill him.

Harmon was taken to the Sauk County jail. A hearing is set for July 13.
