A police dog followed a trail of blood through a Haverhill neighborhood Tuesday night, leading police to two male suspects in a stabbing, State Police said.
The two suspects were seen running from the area of High and Temple streets at about 11 p.m., State Police said in a posting on their blog.
Haverhill officers located blood splatters in the area, and State Police used a K-9 unit dog to follow the trail of blood, State Police said.
The dog followed the trail through a neighborhood to the back door of a house, where a trooper observed more blood spatters on the back porch and door handle, police said.
The trooper and the dog then entered the home and found the two suspects in the basement, police said. Both males were placed into custody and turned over to the Haverhill police.
The identities of the two suspects were not immediately available.
No further information was immediately available.
