Marietta, O., Jan. 12.—Rewards totaling $2,500 are offered for the arrest and conviction of the murderers of Patrolman Harrison L. Boyd, who was shot down in a gun battle with yeggs [yegg--slang term for a criminal, especially a safecracker or burglar] early Sunday morning.

The county offered $1,000, the city a like amount and $500 was posted by the American Legion post here.

Police and county authorities in Marietta and nearby cities are still searching for the slayers, and the West Virginia state police, along with private detective agencies, are assisting in the hunt.

Bloodhounds were brought from Smith-field, W. Va., and traced the killers' tracks to the West Penn interurban station, in the southern part of the business section, where trace was lost.

Officials believe the men escaped in an automobile, as the animals returned and retraced the tracks to the same point. There are believed to have been three men in the armed band.

Patrolman Boyd was making his rounds on the darkest part of his beat and had come through the Baltimore and Ohio railroad yards and approached the Studebaker sales room, which is opposite a blacksmith shop.

As was his custom, he flashed his light on the door, intending to try it, when a gunman lookout near the blacksmith shop, across the street opened fire.

Boyd returned the fire and shot eight times before falling dead.

One unexploded shell was found in Boyd's revolver. The yegg had shot at least eight times, as that many empty shells were found around the blacksmith Shop.

Later on investigation revealed that the safe of the automobile concern was opened and papers scattered about. There was no money in the safe.

Three persons who saw the gun battle from a distance told how the gunmen, after the policeman fell dead, ran into the Pennsylvania railroad yards and disappeared.

Tools used to pry open the safe were stolen from the blacksmith shop, further investigation disclosed.

The shooting, which occurred about a block from the police station, climaxed a ten-day reign of robberies in the residential and business [sections] here.

Only an hour before two robbers held up Jesse Baylock, took $11 from him and told him to rung "for his life!"

He followed orders as they rammed two guns into his ribs. This holdup occurred in the residential hill district.

Police in Marietta and Belpre, O., and Williamstown and Parkersburg, W. Va., have been on edge for the last ten days because of the series of robberies in the four towns, and are co-operating in an effort to catch the murderers.

A bloody handkerchief and a chisel form one clew [sic.]. Another, not yet in the hands of police, is a stolen automobile, in which the yeggs escaped.
