Officer Dingus is executing a valid search warrant in the home of Mr. E. The warrant allows Officer Dingus to enter the home for the purpose of looking for a stolen 65" television. Officer Dingus is aware that only the television was taken, as the owners had to use their phones as remotes due to their dog having eaten the physical remote.

After Officer Dingus enters the living room, he opens a small cabinet and observes a mobile meth lab inside. He seizes the meth lab materials as evidence and arrests Mr. E on manufacture charges. He does not find any evidence of the stolen television.

Is Officer Dingus's seizure of the meth lab allowed? Why or why not?
