A Denver Police Department administrative review released Friday concluded there is insufficient evidence to support a Denver man’s allegations of police misconduct in a 2009 beating.

Alexander Landau, 23, was the driver of a vehicle pulled over for an illegal left turn in the early morning of Jan. 15, 2009. An ensuing struggle left Landau with severe injuries, pictures of which resulted in outrage and community protests.

“How is this going to impact good and bad officers? What type of message does it send to their department?” said Landau, who now works with the Colorado Progressive Coalition, a community advocacy and outreach organization.

The Justice Department, which conducted a separate investigation, notified Landau in February that it would not charge Cpl. Randy Murr and Officers Ricky Nixon and Tiffany Middleton with civil-rights violations stemming from the case, citing a lack of evidence.

A federal lawsuit against the city filed by Landau alleged that officers hit him with their fists, flashlights and a radio, and called him a racial epithet during the beating.

The lawsuit also alleged that the three officers attempted to cover up the beating, which left Landau with “persisting neurological damage.”

The suit resulted in a $795,000 settlement in 2011, the second-largest in the city’s history.

The DPD review concluded that there was no evidence of a cover up, and stated that ,”Physical evidence, including Landau’s injuries, is consistent with all accounts of the incident and is not ultimately helpful to the determination.”

Denver Manager of Safety Alex Martinez said that the more than 1,000 documents and 40 hours of audio and video from the review will be made public through the department’s records coordinator.

“I honestly believe that anyone who takes the time to go through all of that information, and who does so without preconceived notions … inevitably comes to the same conclusion that there just isn’t evidence there to find that there was serious conduct on the part of any of the officers,” Denver Manager of Safety Alex Martinez said Friday.

However, Independent Monitor Nicholas Mitchell said late Friday that while he agrees evidence in the case “create significant ambiguity about what occurred,” he is troubled that allegations that an investigator in the Department’s Internal Affairs bureau “sought to intimidate and dissuade (Landau) from pursuing his complaint” have not been properly investigated.

Landau years ago reported that “internal Affairs suggested that he was bringing false charges, summarily dismissed his allegations of racial slurs, accused him of playing the ‘race card’ and otherwise conveyed that the incident would not be fairly investigate,” Mitchell wrote in an e-mailed statement.

“I was disappointed to hear the manager, in his press conference today, indicate that today’s decision marks the end of the administrative investigations and employment actions related to Mr. Landau,” he wrote. “I do not believe that Mr. Landau’s complaint will be fully addressed until the alleged bias in the Internal Affairs intake interview has been investigated and resolved.”

Murr was fired for lying on a police report in a separate police beating case in April 2009. Nixon was fired in 2011 for lying in a police report about a violent 2009 incident caught on video outside the Denver Diner, but was later reinstated.
