The Trempealeau County Sheriff's Department is asking for your help in their investigation on a fatal hit and run in Arcadia

The sheriff's department says they want information on any contacts with 50-year-old Robert Kreibich or observations of his vehicle last Sunday.

Kreibich is accused of the hit and run death of 5-year-old Matt McKay who was sledding on a hill in front of his home.

The sheriff's department is asking anyone who has information on Kreibich's whereabouts last Sunday or his vehicle, an early 90's Grey Buick Century four door Sedan to call the department.

A suspect in the hit-and-run death of a 5-year-old Arcadia boy who was killed while sledding Sunday has appeared in court.

A Trempealeau County judge set bond at $100,000 for Robert Kreibich, after deputies say he hit the boy and fled the scene.

The Trempealeau County sheriff says five-year-old Matt McKay was sledding down a hill in front of his home Sunday afternoon, when he slid into the road and was hit by kreibich's vehicle.

Now, the family of Matt McKay is mourning the loss of a boy they say was curious and full of energy.

McKay's uncle says his nephew was the family joker: a child who loved life, loved school and had an infectious laugh.

But an afternoon of sledding on this hill outside the McKay family home on Soppa Road in Arcadia turned tragic Sunday.

Trempealeau County Sheriff Richard Anderson says the fatal crash happened shortly after 3:00 p.m.

"There's an area next to the roadway, the hill next to the roadway, where the boy was sliding down a small embankment and came out onto the highway," Anderson said. "The vehicle was headed south on Soppa and struck him."

Anderson says Robert Kreibich of Arcadia was driving that vehicle and took off after the crash.

He says Matt was pronounced dead at the scene.

"In rural areas where it's unmarked, the limit is 55 miles per hour," Anderson said. "However, that depends on the condition of the roadway."

He says the condition was snow-covered and slippery but is not commenting on other details surrounding the crash.

Anderson says his department was given Robert Kreibich's name as the possible driver.

"We followed up on it, found the vehicle and subsequently talked to him," Anderson said. "He was taken into custody where he is now."

A judge set Kreibich's bond at $100,000 with conditions that if he posts bond, Kreibich cannot possess alcohol, enter a tavern or have contact with the McKay family.

A family in the grieving process for a boy they say they'll remember for his caring, deep brown eyes.

Anderson says more charges are forthcoming, as the sheriff's department continues to investigate.

Kreibich has three drunk driving convictions on his record.

The family has set up a memorial fund at the State Bank of Arcadia, under the name "Matthew McKay."
