He injects a noxious liquid into the threshold using a syringe. That same chemical odor later made the family inside — husband Umar Abdullah, his wife, and their infant — sick. Investigators say Li later admitted he wanted to “end the noise” from footsteps, furniture, and a crying baby above. Between May XX and June 27, 2023, the Abdullahs suffered ongoing symptoms including headaches more severe than migraines, nausea, shortness of breath, skin and eye irritation, and their baby losing clumps of hair. Smoke alarms prompted fire department inspections that found no gas leaks.
