02 Road Rage Gunman Kills Mother of 4

Police are working overtime to track down the gunman behind the road-rage killing of a mother of four Sunday afternoon as she and her husband returned home from a supermarket to watch the Oakland Raiders game.

Perla Avina, 30, was in the passenger seat when an angry motorist pulled along side their Toyota Camry and fired several shots, striking her in the head.Her husband, Luis Lopez Gallegos, raced to their East Oakland home a few blocks away to summon help.

Avina died in the driveway as Gallegos shouted to a neighbor to call 911.

The young shooter was “a coward with a gun” who “doesn't care about life,” Gallegos told the Oakland Tribune.

He couldn't recall exactly what precipitated the shooting,only “another motorist not liking the way he drove,” the paper writes.

Gallegos, a mechanic, said he and his wife had been high school sweethearts before marrying and starting a family.Their children ranged in age from 14 years to 18 months.

A reward of up to $30,000 is being offered for information leading to the suspect's arrest.Businesses along 98th Avenue were urged to check their security video.

Avina scheduled surgeries at a clinic in nearby Emeryville, where she had worked for eight years.

“A shining spirit.Always postiive, always had a smile on her face,” her manager, Darlene Cederborg, told KTVU-TV.

Avina's family is seeking help to pay for her funeral.More than $26,000 had been donated by Tuesday evening.

The fundraising page cites two of her favorite sayings:

“The most precious jewels you'll ever have around your neck are your children's arms.”

“Take care of the people you love but take even better care of the people who love you.”
