MADISON, WI (WTAQ) - Madison police say they are looking for 24 year old Edgar Ivan Salinas-Leal in connection with the city’s first homicide of 2012.

An apparent argument between the suspect and his landlord ended with the landlord shot to death Friday night.

Salinas-Leal is thought to be with his wife and their infant son – and police say there is concern for her safety and that of the baby.

It isn’t clear if they went with the murder suspect voluntarily.

It is believed Salinas-Leal stole the victim’s minivan when he left the scene. Neighbors identify the shooting victim as 38 year old Darrell Ballweg.
