Denver Post Story: Family worried about missing Westminster man
Westminster resident Jeremy Griess disappeared on April 11 and family members are asking for the public’s help locating him.
Griess left his Westminster home last Sunday, family members said. They believe he was driving his black, 1999, two-door Honda Accord equipped with a roof rack. Cellular “pings” from Griess’ phone put him in the Woodland Park area on Monday with an additional “ping” from an unknown tower two hours later.
“If people can really be on the look out it would really help us,” said Amy Cannella, Griess’ sister-in-law.
Westminster Police have been working with the family, said Cheri Spottke, police spokeswoman.
“We’ve exhausted all law enforcement resources,” Spottke said.
A final cellular “ping” hit the unidentified tower on Wednesday, she said, and no financial activity has been detected on Griess’ accounts since his disappearance.
Family members are searching and exhausted, Cannella said, and concerned Griess is injured.
“He’s an avid fisherman, a biker, and outdoorsman,” Cannella said. “We’re getting a little despondent and running out of time.”

Help Find Jeremy Griess

I saw on the victims heartland that you had a ID for the unknown tower. I contacted a friend of mine that works on the hardware side of cell phones for a smaller company and he is checking with his contacts at other companies to see if anyone they know knows about the tower (it was ID as “LAC 15201” from what I read)
He also had a long shot method that may work for using an Iphone to check which tower is being pinged in real-time instead of via texting records I read were being used. Might be worth a try though he can’t guarantee it will work.
Haven’t seen Jeremy since college, but my prayers are with you all.
“One thing I thought of would be to take an iPhone out there and put it in DEBUG mode. The display shows the cell ID. However, it’s in HEX and may not correlate to the 15201 you were given.
You can put the iPhone in DEBUG mode as follows (works for many GSM-based phones):
*3001#12345#* then hit [Call]
Then check the UMTS Cell Environment -> UMTS RR Info or GSM Cell Environment – > GSM Cell Info. We don’t know if his phone was on GSM or UMTS. 15201 is is 3b61 in hex, so look for that on the display somewhere.”

Thank you for your comment. We have looked into the LAC 15201 and CID 1111. In talking with an AT&T cell engineer, these do not give us a specific location and actually mean that the tower is trying to locate Jeremy’s phone.
