It was a busy afternoon at the Tacoma Costco yesterday, but the excitement was in the parking lot, where gunshots fired in a domestic dispute nearly hit a toddler. One of the bullets, a .45-caliber slug, struck the 2-year-old boy's car seat. The bullet missed the child, but he was cut by flying glass, terrifying his mother and onlookers who thought the boy was shot.

"Somebody's watching over him," Tacoma police Officer Mark Fulghum said.

Two men were booked on suspicion of assault, and the boy was being treated last night at St. Joseph Medical Center for minor injuries.

According to police, the drama began around 3:40 p.m., when a woman having lunch with her boyfriend was confronted outside the store by her ex-boyfriend, who arrived with their son, the 2-year-old.

After they argued and the ex-boyfriend allegedly slapped the woman, the current boyfriend took a gun from his Toyota Tercel, police said.

The ex-boyfriend got into his Toyota 4Runner and with his son strapped into a car-seat inside raced through the parking lot and rammed into the Tercel.

As the 4Runner approached, the man with the gun fired two shots at the vehicle, police said.The woman then called her ex-boyfriend, reaching him on his cellphone as he raced their bleeding son to the hospital. At the hospital, it was discovered that the bullet had missed the boy but hit the car seat.
