Anchorage police say a dispute during a drug transaction preceded the shooting deaths of two men Monday on the city's west side.
Police at 12:30 a.m. took calls reporting shots fired and a vehicle chasing another on west Tudor Road.
Police found the body of 22-year-old Jeramyha Talauega near railroad tracks west of Spenard Builders Supply.
Twenty minutes later, 33-year-old Robin Porter died of a gunshot wound at an Anchorage hospital.
His wife, 32-year-old Meghan Porter, told police she and her husband had met with Talauega to sell him drugs. A dispute broke out and all three fired shots.
Meghan Porter is being held on suspicion of second-degree murder, manslaughter and drug misconduct.
Police are seeking the driver of the vehicle in which Talauega arrived.
