On Saturday June 13th beginning at 2 p.m., Mulligan’s Pub and Grub in Farmington Hills is asking the community to pay $20 at the door, with all proceeds going to help cover funeral expenses of the four victims killed in a shooting at a home in Livonia. Robert McKiddie, the bar’s owner, said Sterling Pierce was a longtime regular he first met years ago when he worked at the bar as a bouncer.
