In a gut-wrenching development that’s gripped the tight-knit coastal community of Mandurah, south of Perth, Western Australia Police have issued a fresh, urgent appeal as the search for missing 15-year-old Emma-Lee Kowalski enters its second week.

The teenager – known to friends and family simply as ‘Lee’ – disappeared without a trace on Saturday, February 14, 2026, the day the nation was celebrating Valentine’s Day. What should have been a day of love and romance turned into every parent’s worst nightmare when the schoolgirl failed to return home, sparking one of the most intense missing persons investigations in the region’s recent memory.

Emma-Lee was last seen in the Mandurah area early that Saturday morning. Police say she was sighted again the following day, Sunday, February 15, around 10:40 a.m., walking on Barrack Street in nearby Perth. She was described as wearing a blue top, black shorts, and carrying a backpack – but since that fleeting glimpse, the trail has gone ice-cold.

With every passing hour, concerns for her welfare intensify. At just 15, Emma-Lee is considered highly vulnerable, and officers stress that time is of the essence in cases involving young runaways or those potentially in danger.

Described as having distinctive long brunette or reddish hair, Emma-Lee is believed to prefer casual, comfortable clothing and is known to use payphones for contact – a detail that’s raised eyebrows among investigators and online sleuths alike. Police have deliberately withheld further specifics about her last known movements or clothing to protect the integrity of the investigation, but the message is crystal clear: if you’ve seen her, or even think you might have, call now.

Mandurah Police have ramped up patrols across the Peel region, launched widespread community alerts, and are working closely with Crime Stoppers. The public appeal is stark: contact Crime Stoppers on 131 444 – anonymously if preferred – with any information, no matter how small. A single tip could be the breakthrough that brings her home.

The disappearance has sent shockwaves through Mandurah, a picturesque coastal city famous for its stunning waterways, family-friendly beaches, and relaxed lifestyle. Known as the “holiday capital” of Western Australia, with its canals, dolphin cruises, and vibrant waterfront, the area is usually synonymous with sunshine and safety – making Emma-Lee’s vanishing all the more heartbreaking.

Online, the community has united in grief and determination. The hashtag #FindEmmaLee has exploded across social media platforms, with thousands sharing her photo, pleading for sightings, and offering support to her devastated family. Friends have posted emotional tributes, describing a bright, popular girl who loved hanging out with mates and was always quick with a smile. Neighbors in the family-oriented suburbs have organized shares, flyers, and vigils, refusing to let the search fade.

One heartbroken post from a family friend read: “It’s been days with no word. None of her friends have heard from her. Bank accounts untouched. This isn’t like Lee. Please, if anyone knows anything…”

Western Australia Police have confirmed ongoing inquiries, including reviewing CCTV from Perth’s CBD and tracing possible movements beyond Mandurah. While no foul play has been officially declared, the extended absence of a young teen has fueled growing unease. Experts note that teenagers sometimes run away due to personal struggles, family issues, or peer pressure – but the lack of any contact has amplified fears that something more sinister could be at play.

Mandurah’s close community has a history of rallying in crises, and this case is no exception. Local Facebook groups buzz with updates, theories, and calls for vigilance. Some residents report checking parks, beaches, and shopping centers themselves, desperate to spot the long-haired teen in the blue top.

As the search drags on, questions swirl: Did she leave voluntarily? Was she lured away? Or has she fallen victim to something unthinkable in the days following Valentine’s? Police urge the public not to speculate but to focus on facts and forward every possible lead.

Emma-Lee’s family remains in torment, clinging to hope amid the silence. Her mother and loved ones have not yet spoken publicly in detail, but the pain is palpable through the shared appeals flooding social media.

This is the nightmare that haunts every parent: a child vanishing on what should have been an ordinary day, in a place that feels safe. Mandurah’s canals glisten under the sun, its beaches beckon families, yet right now, one family’s world has stopped turning.

Anyone with information – a sighting, a conversation, a suspicious vehicle, anything – is begged to come forward. No detail is too small. Emma-Lee could be anywhere: back in Perth, hiding out locally, or further afield.

The clock is ticking. The community is watching. The plea is simple and urgent:

Find Emma-Lee. Bring her home.

Police and Crime Stoppers remain on high alert. We will update this developing story as more details emerge. For now, the message from a heartbroken town is unanimous:

Lee, if you’re out there – we love you. Come home. We’re waiting.
