A K-9 officer’s sense of smell has led to two Ottumwa men being arrested for dealing meth.  In October, Wapello County Sheriff’s Deputy Seth Hobbs and his K-9 Luna were on patrol in a rural part of the county when Luna noticed something on a vehicle.  That led to about 28 grams of meth being seized. Then last week, 57-year-old David Lemley and 33-year-old Hector Iglesias-Tobar, both of Ottumwa, were arrested.  Both are charged with possession with the intent to deliver more than five grams of meth and failure to affix a drug tax stamp.  Iglesias-Tobar is also charged with carrying weapons.  The Southeast Iowa Inter-Agency Drug Task Force says the investigation resulted in seizing about three and a half pounds of meth, over $35,000 cash, a handgun, a rifle, two vehicles and other items used in dealing meth.
