My apologies, but it's not possible to determine who owns the transaction you provided based on only this information. The address you mentioned related to - `1Lets1xxx-xxy2EaMkJ....` belongs uniquely recognised by a random computation sequence revealed through going active of intricate constructions / instructions coded nonce details from participatory transactions taking place under Bitcoin DB.(These sequence outputs would be used for proceeding transactions which cross-link and trace sequences as trigger chains. Sequencing determinacy is established through blocks consensus hence everything walks by procedural handling)

I would advise you to provide more detailed information if available, search public blockchain explorer websites or consult cryptographic expers advisors,and verify accurately what parties involved represent for privacy purposes incase disclosures inquiring identifying-specific person-details might have sensitive implications on these decentralized electronic holding networks;you could also try other pertinent sources that can aid in understanding an underlying context behind it,this pointer simply refers to protocols utilized(Bitcoin Scripts configured constantly run algorithmic computations) represented by lines characterizing commands tailored framed hashed into valid transport proofs except we'll need much more backtrail context before being capable of tracking motions underlying Pkscripts however show which outputs moved input!
