Even though disputes with neighbors can be quite challenging, one family claims that after their neighbor complained about noise, they made a terrible discovery.

In June 2022, Umar Abdullah and his pregnant wife moved into their apartment in Tampa. The neighborhood welcomed them with open arms.

The pair soon started getting texts from a downstairs neighbor, Xuming Li, who was complaining that he was losing sleep because he could hear the toilet seat being adjusted.

For months, the neighbors had argued.

Then Abdullah and his wife claimed they became queasy and nauseated in their apartment, as well as experiencing vomiting.

Abdullah told WFLA: “I look at my daughter. Her eyes were full of tears. She was not crying, but her eyes were full of tears."

A friend of the couple was the first to notice that something might not have been right. While the family was on vacation, he had been traveling around to collect a package for them.

He said, however, that he smelled something upon entering the apartment. He called the smell 'obnoxious'.

They contacted the air conditioning firm but were unable to identify any issues with the system. He again requested the services of a plumber to inspect the water heater, but once more there were no problems found.

Even the heater was changed, and the landlord had the vents and air ducts cleaned. The 'obnoxious' odor was still present, though.

Abdullah contacted the fire department, but their investigations turned up nothing as well.

He continued in spite of everything and set up a camera outside the apartment's front entrance.

Abdullah has now asserted that video from the camera shows Li injecting a substance under the front door after filling a syringe with fluids.

He told WFLA: “We were shaking. We can’t imagine that he is coming and doing something.”

The family left the apartment as soon as possible and dialed the police. Following a hazmat test, it was discovered that the material was a mix of the narcotic painkillers methadone and hydrocodone.

Since then, Tampa Police have detained Li in relation to a variety of felony allegations. Possession of a restricted substance is one of them. Abdullah and the condo are suing him for contract breaches, and he is also being sued for domestic violence.

Li was listed as a University of Southern Florida Ph.D. student in chemistry, however, the school has confirmed that he was removed from the list after the summer semester concluded in 2023.

He entered a not-guilty plea to the accusations.
