Tik Lam, 71, disappeared from his Philadelphia home on the 800 block of Locust Street on November 13, 2012, last seen about 4 p.m. He had dementia, did not speak English, and had recently moved to Philadelphia from New Jersey. At the time he vanished he was 5 feet 4 inches, about 125 pounds, with graying black hair and brown eyes. He wore a blue flannel shirt, black vest, blue jeans, blue sneakers, a jade heart-shaped necklace and a Seiko wristwatch engraved with his identification; he also carried a New Jersey ID card.

There were a few potential sightings early on. One placed an elderly Asian man matching his description walking along a highway in the Lower Merion/Tredyffrin area on November 14, more than 13 miles from his home. Another report came from a driver who thought they saw an older Asian man walking across the Benjamin Franklin Bridge into New Jersey. His family thought he could be anywhere within a 150-mile radius, and his dementia and language barrier were cited as major concerns for his safety.

If anyone saw Tik Lam around November 13–14, 2012, or knows of someone who might have helped an elderly man fitting his description, please share information with the Philadelphia Police Department.
