Eau Claire Leader (Eau Claire, WI) 1 Nov 1904
Killed at Charivar
(Rice Lake Chronotype)
A dispatch from Grantsburg, dated Oct. 24, stated that while a party of men and boys were giving him a charivari, Marcus Blood shot into the crowd killing a 10-year-old boy.The shooting occurred at Hertel.
Blood was taken to Grantsburg Saturday by Undersheriff Christensen and when arraigned he pleaded not guilt.The hearing was set for the 25th, and we have not learned the findings of the court.
Mr. Blood formerly resided at Canton and is well known to many of our readers, who will be sorry to learn of such a sad outcome of a serenade party.

Marcus Blood Got Six Months
Fired Shot Into a Crowd of Young Men in Burnett County
Youth of Twelve Years Dies From Effects of Bullet Wound
Rice Lake, Wis. –Special to the Leader—Last summer a young man by the name of Marcus Blood, a son of I. P. Blood, a pioneer settler at Canton, Barron county,while attending a wedding in Burnett county, fired a revolver shot into a charivari, the bullet striking and killing a lad twelve years of age.Mr. Blood, who was arrested, claimed that he did not fire the shot, but at his trial held last week, the jury found him guilty of homicide in the fourth degree and sentenced him to a term of six months in the county jail.
There was some doubt as to who fired the shot, but the circumstantial evidence pointed to Blood, who if guilty of firing the shot, was not guilty of premeditated murder, and probably fired the shot for the purpose of frightening the party making the noise without any thought of injuring any one, much less killing one of the party, it being an accident as far as intent was involved.Guilty or not guilty , the accident, if such it was, and the punishment meted out tothe unfortunate young man, should have the effect to make all more careful in handling firearms and in firing promiscuously, for it is extremely dangerous and verifies the old saying that a gun destitute of lock, stock or barrel is dangerous.
