A man and woman were being sought by authorities after surveillance video showed the man get out of an SUV, place a dog on the ground and shoot the animal twice, killing it, then driving away.

The shooting occurred at 16450 Phoebe Ave. around 12:45 p.m. Sunday, according to the Los Angeles County Sheriff's Department's Norwalk Station.

A witness told deputies the man got out of the passenger side of a white Jeep Grand Cherokee and placed something on the ground near the gutter, then fired two shots. The suspect got back into the Jeep and both suspects drove away southbound on Phoebe Avenue, then turned left on Firestone Boulevard and out of view, the LASD said.

The witness then found a dog dead from gunshot wounds lying on a dog bed in the gutter, the department said.

Anyone with information was asked to call Detective Mark Christiansen of the Los Angeles County Sheriff's Department at 562-466-5419.

The animal-advocacy organization PETA has offered a $5,000 reward for information that leads to the suspects.
