Snohomish County deputies first responded to a burglary call at 5:30 p.m. in the 300 block of South Carpenter Road. When they arrived they found a man with an apparent gunshot wound to the leg.
Witnesses say as many as seven people were involved in a burglary attempt that ended in gunfire. Deputies shut down part of Carpenter Road for several hours while they searched for the shooter.
During the hunt, they detained and released at least four people before they arrested the alleged shooter. That man, who is not being identified, is facing a first degree assault charge, according to deputies.
While looking for the shooter, deputies found several hundred marijuana plants, but it's unclear if they're related to Friday's incident.
No other arrests are expected in the case.
