The Coast Guard informed that an oil-slick reached across miles and miles of land from Imperial Beach south into Mexico is now a good portion cleared and its source is still a mystery.  

Coast Guard spokesman Bill Burwell said a flyover of the slick Sunday afternoon showed that it had  ”pretty much dissipated” from U.S. waters.

The oil slick was called in around 11:30 a.m. Saturday by a recreational boater who said there was an oily covering blanketing the water about six miles off Imperial Beach. The sheen contained the colors of the rainbow, causing him to believe it was a petroleum base less dense than diesel or other fuels.

The oil slick reached about half-mile wide stretching west for 15 miles, then south into Mexican waters.

Burwell reported that the  Coast Guard is working alongside Mexican authorities to find the source.

San Diego County Crime Stoppers announced that they will be giving a reward of $1,000 for any beneficial information that would allow them to find the culprit and those guilty of pouring oil on a freeway off-ramp Tuesday afternoon, an incident which resulted in a fatal crash. 

 Jose Ismael Lerma was driving in his Ford Expedition when he hit an oil patch and collided with a trash truck on Federal Boulevard after fishtailing and losing control of the car on the Federal Boulevard off-ramp from eastbound state Route 94.

Lerma, 36, a resident of San Diego, was both a husband and a father. He passed away at the hospital shortly after the incident. There were reports of other cars that hit the oil patch causing them to slide and crash. 

Four 5-gallon buckets of used oil were poured onto the off-ramp at some point before the accident occurred.
