Menomonee Falls police issue statewide alert for 28-year-old last seen at Milwaukee Mitchell Airport Friday

Statewide alert issued after man last seen at airport

Menomonee Falls police have issued a statewide missing-person alert for Gurnoor Singh Kier, 28, after investigators said he was last seen Friday, February 28, 2026, at Milwaukee Mitchell International Airport.

Authorities said Kier left his home that day using a ride-share service and was later seen at the airport at about 6:44 p.m. Police said he told someone he was heading from the airport to a hotel in Milwaukee, but his current location remains unknown.

Description and known last details

Police described Kier as 6 feet 3 inches tall and about 375 pounds, with short black hair and black eyes. He was last seen wearing a navy blue track jacket and black slippers.

Investigators said Kier has diagnosed mental health conditions, including bipolar disorder and schizophrenia, and may have difficulty caring for himself without assistance. Law enforcement has not released additional details about an intended destination beyond the statement that he indicated he was traveling from the airport to a Milwaukee hotel.

How missing-person alerts are distributed in Wisconsin

In Wisconsin, local law enforcement agencies can issue statewide bulletins through the Wisconsin Crime Alert Network, a system used to distribute missing-person and crime alerts to registered recipients. The network is designed to quickly share identifying information and last-known details that could help locate a missing person.

Separate alert programs exist for specific circumstances, including AMBER Alerts for abducted children and Silver Alerts for missing older adults with dementia or similar cognitive impairment. When cases do not meet the criteria for those programs, agencies may still request broad distribution through statewide alert systems used for missing-person notifications.

Law enforcement presence at Milwaukee Mitchell International Airport

Milwaukee Mitchell International Airport is policed by the Milwaukee County Sheriff’s Office Airport Division, which provides law enforcement services across the airport complex on a 24/7 basis and coordinates with airport operations and federal partners operating on-site. When a missing-person investigation includes an airport as the last confirmed location, coordination can involve reviewing surveillance video, confirming transactions and passenger activity when available, and checking potential off-airport travel paths.

What the public can do

Police are asking anyone who has seen Kier or has information that could help locate him to contact the Menomonee Falls Police Department. Authorities have not said whether Kier boarded a flight, left the terminal, or reached a hotel after the reported airport sighting.

If you believe you have relevant information, provide a location, time, and description of what you observed, and report it directly to law enforcement.
