Officers are asking for the community’s help searching for a 68-year-old man with diagnosed dementia who was last seen Saturday afternoon in Signal Hill.

The Signal Hill Police Department describes William Harville as a Black man who stands 5 feet and 8 inches tall, weighs about 162 pounds, and has gray hair and blue eyes.

He was reportedly last seen around 2 p.m. with a known associate leaving the Courtyard Care Center Assisted Living facility located at 1880 Dawson Ave.

The department says Harville was wearing a brown beanie, a blue long-sleeve shirt, brown sweatpants and sunglasses.

Officers did not immediately provide any details as to how Harville went missing, or if the known associate provided any further information.

Police ask anyone who may have seen Harville or have any information regarding his whereabouts to call the Signal Hill Police Department at 562-989-7200.

Another package has been reportedly intercepted in Los Angeles County, making it the third expensive laptop delivery to be stolen in Southern California this November.

This time, however, rather than swiping it in front of a consumer’s home – the thief went a few steps further.

“I ordered a laptop online and I did it for in-store pick up because I didn’t want it to get stolen,” the consumer, Rick Markowitz, told KTLA’s Jennifer McGraw on Saturday. “And I said, ‘Hey, I’m here for my in-store pickup,’ and immediately they go, ‘Your laptop was already picked up sir,’ and I’m like, ‘What are you talking about? I’ve never come to pick it up.’”

Markowitz now says he’s out $4K after the imposter picked up his computer from an Apple Store in Sherman Oaks on Tuesday.

While he was still at the store, Markowitz says he asked the staff if he was hacked.

“They said, ‘Well we don’t know if you were hacked or not, but we’re saying someone with an ID with your name on it came in and picked up the laptop.’”

Markowitz later filed a police report and then, deciding to do some research of his own, he went online to see if this incident had happened to anyone else recently.

In his searches, he found KTLA’s report from Nov. 28 about a thief who police believe posed as a consumer, showed an ID to the delivery person, and then walked off with someone else’s package – in two separate instances.

“And I’m like, wait, am I the third incident of someone who has a laptop intercepted and tracked specifically from Apple?” posed Markowitz. “And mine was in-store, which is crazy.”

Unlike the other two instances, security footage was not immediately made available for Markowitz’s case. However, the similarities between each of the three incidents raise concerns for residents, as well as experts.

“In essence, this is identity theft,” claims Randy Sutton, a retired police lieutenant and crime prevention specialist who believes these victims have been hacked.

“Making a fake ID is a walk in the park, especially when you’re dealing with people who are sophisticated,” says Sutton.

He says in these three cases, scammers likely hacked the victims’ cell phones, getting the tracking information and potentially making an ID.

Police did not immediately say whether this incident is believed to be connected to the other two Southern California cases.

To see if your phone has been hacked, Sutton advises consumers to visit malwarefox.com, a website that he says lists “all of the different methodologies used to compromise your information.”

And Markowitz, who thought he was doing everything right, is hoping to warn shoppers.

“Now as a result, I have to beg and kick and scream up the Apple ladder just to get them to give me a refund for the laptop that was never handed to me,” cautioned Markowitz.

Sutton says in these cases, the credit card companies commonly take the brunt of the fraud, and generally, consumers are usually reimbursed.
