United States v. Lieu
298 F. Supp. 3d 32
D.C. Cir.2018Background
- Defendant David Lieu was arrested after online exchanges with an undercover detective posing as a father of a nine‑year‑old; chats and a bar meeting arrangement led officers to arrest him at the meeting location.
- Officers seized Lieu’s cell phone at arrest and later obtained a warrant to search his New York home; the home search yielded an external hard drive containing hundreds of child‑pornography images and videos.
- Forensics of the phone showed (1) the chats with the undercover detective (including transmitted images), and (2) contemporaneous chats with a different user (John Doe) in which Lieu described prior sexual contact with his stepdaughter and expressed eagerness to meet a nine‑year‑old.
- The stepdaughter later told investigators Lieu had sexually abused her between ages seven and ten.
- Procedural posture: Lieu moved to suppress the phone, statements, and items seized from his home (arguing Fourth and Fifth Amendment violations and a defective warrant); the government moved to admit prior‑bad‑act evidence (possession of child pornography, prior molestation of stepdaughter, and the John Doe chats) under Rules 404(b) and 414.
Issues
| Issue | Plaintiff's Argument (Government) | Defendant's Argument (Lieu) | Held |
|---|---|---|---|
| Lawfulness of warrantless public arrest and search incident to arrest | Arrest was supported by probable cause given totality of facts known to officers (timing, clothing description, name exchange, approach at bar) | Officers lacked probable cause because they could not be certain Lieu was the message sender; clothing and common names insufficient | Denied suppression: probable cause existed based on totality of circumstances; search incident to lawful arrest and seizure of phone valid |
| Admissibility of post‑arrest statements (Miranda) | Agents read Miranda; Lieu waived rights knowingly, intelligently, voluntarily and agreed to selectively answer questions | Lieu initially invoked counsel and therefore later statements are involuntary and should be suppressed; warrant relied on tainted statements | Denied suppression: waiver was valid (oral and written warnings; Lieu expressly waived after initially requesting counsel) |
| Validity of New York search warrant (Franks/omission) | Warrant affidavit properly supported probable cause independently of Lieu’s statements; no knowing omission or falsehood requiring Franks hearing | Warrant was tainted because agents omitted that statements were procured despite Lieu’s invocation of Miranda; warrants therefore defective | Denied suppression: no Franks showing; even excising Lieu’s statements affidavit still gave fair probability that evidence would be at his NY residence; Leon/ Gates analyses support validity |
| Admission of prior‑bad‑act evidence (404(b) and 414) | Evidence of possession of child pornography, prior molestation of stepdaughter, and contemporaneous John Doe chats are probative of motive, intent, knowledge, and absence of mistake; Rule 414 applies to count charging distribution | Such evidence is unfairly prejudicial and should be excluded under Rule 403 | Granted in part: court admits all three categories (404(b)); possession and stepdaughter abuse also admissible under Rule 414 as prior child‑molestation for the distribution count; admission subject to limiting instruction and trial‑level 403 balancing on specific exhibits |
