The Los Angeles County Sheriff’s Department is asking for the public’s help finding witnesses after a man allegedly pointed a handgun at numerous passing cars in Castaic on June 18.

The man was allegedly seen pointing the gun at cars near Lake Hughes Road and Ridge Route Road between 6 p.m. and 6:30 p.m. The suspect was described as wearing a red shirt and black shorts.

Authorities provided a photo of the man seen running in the street while holding something in his left hand.

Southern California is enjoying a comfortable stretch of below-average temperatures that should continue through Father’s Day, but a strong heat wave is looming.

A significant warming trend will begin early next week before peaking Wednesday and Thursday, according to the National Weather Service.

“Another one of those ridges of high pressure is expected to build in, with temperatures really heating up,” KTLA’s Kirk Hawkins said. “We’re looking at temperatures reaching triple digits in parts of the High Desert and Inland Empire as well.”

An extreme heat watch has been issued for parts of Los Angeles County, including Woodland Hills, Pomona, Pasadena, Santa Clarita and other areas, from Tuesday morning through Thursday evening.

Temperatures in those areas could range from the upper 80s to 100 degrees.

The Weather Service suggested the following actions:

• Continue to monitor the latest forecasts, as the amount of heating is still uncertain
• Adjust plans now to stay cool next week
• Check in with elderly neighbors and family members to ensure they are aware of the hot forecast

The high-pressure system is expected to weaken on Thursday, bringing cooler temperatures as we head into next weekend.

A 48-year-old man who led law enforcement on a dangerous pursuit lasting more than an hour is in custody in connection with the shooting deaths of a man and a woman at an upscale Pomona apartment complex Thursday, police announced.

Officers with the Pomona Police Department responded to the Monterey Station Apartments, located at 180 E. Monterey Ave., near North Garey Avenue, just before 3:30 p.m. on reports of a shooting, according to a department news release.

Police, along with responding Los Angeles County firefighters, found the two victims in a fourth-floor apartment.

Paramedics immediately began life-saving measures, but both victims were ultimately declared dead at the scene, investigators said.

Neighbors told KTLA’s Mary Beth McDade that the suspected shooter, Robert Galtman of Pomona, shot his girlfriend and another resident of the apartment complex.

“He shot the girl, that was the girlfriend,” one woman, a resident of the building who did not want to give her name, told KTLA. “I know them because he had tried to hit on me and told me the situation that she was beating him up and that she cheated on him with this guy, the one that was killed.”

Authorities were searching Galtman, who was believed to be in dark-colored sedan that fled the apartments northbound on Towne Avenue near Holt Avenue.

Just before 5 p.m., officers with the California Highway Patrol spotted his vehicle traveling northbound on the 5 Freeway, officials confirmed to KTLA. When officers attempted a traffic stop, he failed to yield and led authorities on a high-speed pursuit that lasted more than an hour.

During the pursuit, he made a U-turn on the freeway and headed southbound before exiting in Castaic and taking Lake Hughes Road through the hills toward the Antelope Valley.

Sky5 was over the dangerous chase as Galtman was seen tossing unknown items from the vehicle, including some type of liquid, swerving dangerously onto the shoulder and refusing to stop as at least four CHP units followed closely behind.

He initially dodged several spike strips deployed by officers, at one point driving on the shoulder in Lancaster before clipping one of the strips with the vehicle’s left side, causing both tires to deflate.

Still refusing to stop, Galtman continued at about 30 mph until a CHP officer accelerated and performed a PIT maneuver that spun the vehicle and disabled it.

He was quickly surrounded by officers with guns drawn but did not immediately comply.

Following law enforcement commands, Galtman exited the vehicle, surrendered and was taken into custody.

The identities of the two victims are being withheld pending notification of next of kin.

Authorities have not released a motive in the deadly shooting. The investigation is ongoing, and anyone with information is asked to contact the Pomona Police Department’s Detective Bureau at 909-620-2085.
