German police have arrested an 81-year-old suspect in the 1994 sexual assault and murder of 24-year-old American tourist Amy Lopez, whose partially nude body was found near Ehrenbreitstein Fortress in Koblenz. Modern DNA testing and the re-analysis of about 1,600 samples produced a match after investigators obtained a fresh saliva sample from the suspect. Tips following a 2024 reward and a TV feature helped revive the probe, and the suspect—previously convicted in 1999 for an attempted rape—is now in pretrial detention in Rhineland-Palatinate.

German authorities announced this week that they have arrested an 81-year-old suspect in the 1994 sexual assault and killing of 24-year-old American tourist Amy Lopez. Lopez's partially nude body was found near the historic Ehrenbreitstein Fortress on the Rhine in Koblenz, and the case remained unsolved for decades until recent DNA advances reopened the investigation.
Discovery and Cause of Death
Children discovered Lopez's body in 1994. Local officials said she had severe head injuries and had been partially unclothed. The Koblenz Public Prosecutor's Office said the victim "was strangled, struck on the head with a stone, and stabbed multiple times, ultimately resulting in her death."
How the Case Was Reopened
Investigators re-examined Lopez's clothing and analyzed roughly 1,600 samples using modern forensic methods. Chief Public Prosecutor Manfred Mannweiler said improved DNA technology allowed police to reopen the file and identify new leads. In 2024—about 30 years after the killing—police offered a €2,500 reward after identifying a male DNA trace. The case also drew fresh tips following a feature on the true-crime television program "Aktenzeichen XY."

DNA Match and Arrest
Prosecutors said the suspect's DNA had previously been recorded after a 1999 conviction for attempting to rape a 16-year-old in Koblenz, for which he received a seven-year sentence. That genetic entry had since been deleted. Investigators were able to obtain a new saliva sample from the suspect—who was arrested in a retirement home—and matched it to DNA recovered from inside Lopez's jeans, the prosecutor's office said.
"Methods have improved since the crime. What is possible today would have been less so in 1994,"
— Chief Public Prosecutor Manfred Mannweiler
Mannweiler added: "There was a nagging fear gnawing at everyone that the case might never be solved. There's relief that we might solve it now." Police notified Lopez's father of the arrest.
Ongoing Proceedings and Investigation
The suspect is being held in pretrial detention at a correctional facility in Rhineland-Palatinate on suspicion of premeditated murder. Senior detective Friederike Manheller-Sander said officers reopened the file after a unit dedicated to cold cases was created last August. "Behind every case there is a person whose life was taken too soon," she said. "Our commitment is to do everything possible to find answers."
The investigation remains ongoing and prosecutors said further forensic and legal steps will follow as the case moves toward trial.
