Update (Tuesday, 4:30 p.m.): Investigators won't know for weeks whether the cyclist who died Sunday in a crash with a snowplow was impaired by alcohol or drugs.

According to Cmdr. Paul Sommer of the Anoka County Sheriff's Office, "it has yet to be determined if alcohol or other chemicals played a role in the death. Toxicology typically takes weeks to get back."

Kerry Steven Baker, 46, was dead at the scene when Fridley police arrived at the scene at 7 a.m. Sunday (about an hour before sunrise) in the 4700 block of East River Road.

In a statement Tuesday, Sommer said the sheriff's office does not suspect alcohol played a role on the driver of the private snowplow truck, which was not plowing snow at the time.

Baker was riding north in the left southbound lane when the southbound truck struck him, according to the statement.

Baker's bike did not have lights and he was not wearing a helmet, according to  Sommer. 

The sheriff's office also said that Baker had no current address.

One of the few pieces of information about Baker to come out Tuesday was his criminal record. According to online state court records, 10 of 13 cases in which Baker was convicted between 1985–2005 involved alcohol, drugs, driving or some combination of those (such as DWI).

Update (Tuesday, 1 p.m.): The Anoka County Sheriff's Office released a statement with more information about the bike-snowplow truck crash that killed 46-year-old cyclist Kerry S. Baker on Sunday morning on East River Road in Fridley. 

Baker’s bicycle did not have any lighting in place and Baker was not wearing a helmet at the time of the crash. Baker had massive injuries including multiple broken bones and internal damage to his organs.

The snow plow was not plowing snow at the time.

The sheriff's statement confirms that Baker was traveling northbound in the southbound lanes of traffic on East River Road, and that the plow was a privately operated. The time of the incident was 6:56 a.m.

The sheriff's statement said Baker had "no permanent address."

Update (Tuesday, 11 a.m.): The Anoka County medical examiner has identified the 46-year-old man killed Sunday when a snowplow truck hit his bike on East River Road in Fridley as Kerry S. Baker.

Baker "died as a result of multiple blunt force injuries sustained when his bicycle collided with a snow plow," according to the Midwest Medical Examiner's Office. 

The Midwest Medical Examiner's Office listed "no current address" for Baker's residence. Authorities have said he was a resident of New Brighton.

He did not have a helmet or a headlight, according to Cmdr. Paul Sommer of the Anoka County Sheriff's Office:

The bicyclist was not wearing a helmet and had no lighting on his bicycle.

The bicycle was traveling northbound in the southbound lane of traffic in the left lane of traffic.

The plow driver was traveling southbound in the left lane of southbound east river road.

The plow driver was a private operator, not a city, county or state plow driver. The plow driver was cooperative with the investigation and it not suspected that alcohol was a factor on the part of the plow driver.

Original post (Tuesday, 10 am.): Fridley police had nothing new to say Tuesday morning about the death of a bicyclist Sunday morning after a collision with a private snowplow truck on East River Road. 

The victim, a 46-year-old New Brighton man, was dead at the scene when Fridley police arrived, according to Anoka County Emergency Dispatch.

The names of the victim, the plow truck driver and the company that the plow truck driver was working for are still under wraps, according to Lt. Mike Monsrud. 

Agencies involved in the investigation include the Fridley Police Department, Anoka County Sheriff's Office, Minnesota State Patrol and Midwest Medical Examiner's Office.

Monsrud said he couldn't comment on aspects of the incident including whether the bicyclist was wearing a helmet, the direction the bicyclist was riding, and whether the bike had a headlight.

Anoka County Emergency Dispatch released a statement Sunday saying that it appeared the bicyclist was traveling northbound in the left southbound lane of East River Road.

The crash happened in the 4700 block of East River Road, between Anoka County Riverfront Park and the Burlington Northern Santa Fe railyard. 

A WCCO-TV report said that the bike did not have a headlamp as required by law and showed Fridley police loading a bike with a crumpled front wheel into the trunk of a squad car. The bike had a child seat and appeared to have a front reflector.
