Was the Mikhail Lesin suspicious death in 2015 investigated by the Washington , D.C. police or the FBI?
Both the Washington D.C. police and the FBI were involved in the investigation into the 2015 death of Russian media executive Mikhail Lesin.
Here is a breakdown of their roles:
D.C. Metropolitan Police Department (MPD): The MPD initially conducted the death investigation, as the body was found in a hotel in its jurisdiction.
FBI: The FBI assisted the MPD and the U.S. Attorney’s Office for the District of Columbia throughout the investigation.
U.S. Attorney’s Office for the District of Columbia: This office was responsible for overseeing the overall case.

The joint investigation was concluded in October 2016. At that time, the D.C. Chief Medical Examiner changed the manner of death from “undetermined” to “accident,” citing blunt force injuries from falls and acute ethanol intoxication. However, this finding has been disputed by others, and Lesin’s death continues to be a subject of speculation.

Under what circumstances does the FBI usually reopen the suspicious death cases? – Google Search google.com/search?q=Under+wh…
Mistakes in the original investigation: If evidence surfaces that indicates the original investigation was botched or inadequate, a new inquiry may be warranted.
–
The FBI is generally not the primary investigator for suspicious death cases, which are typically handled by state and local authorities. The FBI will only open or reopen an investigation in limited circumstances that fall under federal jurisdiction or when local agencies specifically request assistance. [1, 2, 3] 
New and compelling evidence
A case can be reopened, regardless of how long ago it was closed, if new, credible, and exculpatory or inculpatory evidence emerges. This can include:

• Technological advances: DNA testing, improved forensic analysis, or a new database may provide new evidence not available during the initial investigation.
• A new witness or a changed testimony: A new lead from a witness who comes forward years later, or a previous witness who provides new or differing accounts, can trigger a review.
• Mistakes in the original investigation: If evidence surfaces that indicates the original investigation was botched or inadequate, a new inquiry may be warranted. [4, 6, 7, 8, 9] 

Federal jurisdiction
The FBI is more likely to open or reopen a case if it involves one or more elements that establish a federal offense, such as:

• Civil rights violations: The Department of Justice (DOJ) and FBI launched the “Cold Case Initiative” in 2006 to identify and investigate racially motivated murders from the Civil Rights era. The Emmett Till Unsolved Civil Rights Crime Act directs them to review civil rights-era killings.
• Crime on federal land: The death occurred on a military base, national park, or other federal property.
• Federal victim or criminal: The victim was a federal official, or the suspect is a federal fugitive.
• Interstate crime: The crime crossed state lines, such as in cases of kidnapping, or the movement of a body across state borders.
• Serial killing: The FBI can investigate serial killings if requested by state law enforcement. The FBI’s Violent Criminal Apprehension Program (ViCAP) focuses on serial murders and other violent crimes. [3, 10, 11, 12, 13] 

Local request for assistance
The FBI does not take over local investigations. Instead, local law enforcement agencies can request federal support when a case is particularly complex or has exhausted all local resources. This can lead to the FBI’s involvement in a cold case review by providing:

• Specialized resources: The FBI’s lab, behavioral analysis unit, and other resources can provide forensic expertise that may not be available to a local agency.
• Joint task forces: The FBI can partner with local agencies to form a task force to tackle particularly difficult cases. [3, 14] 

The Homicide Victims’ Families’ Rights Act of 2008
This federal law enables the family members of a cold case victim to request a file review by the investigating federal law enforcement agency. For eligible cases, the law requires the agency to review the file if the homicide occurred after January 1, 1970, was previously investigated by a federal entity, and all investigative leads have been exhausted.

Evidence of misconduct or injustice
In rare circumstances, a case can be reopened if there is evidence of misconduct or a botched investigation by the original authorities. Historically, the FBI has also investigated cold cases involving civil rights issues where the original conviction or investigation was considered racially motivated or otherwise unjust.
