Editor’s note: Juan Guerra was acquitted of all charges by a jury on June 15, 2026.
Before DC Superior Court Judge Milton C. Lee Jr. on June 9, a homicide defendant took the stand as the defense’s first witness.
Juan Guerra, 34, is charged with second-degree murder for his alleged involvement in the death of Peter Miller III, 32, who died from blunt force trauma on the 900 block of Maine Avenue, SW, on Oct. 6, 2021. Miller later succumbed to his injuries on Oct. 11, 2021.
Guerra’s attorney, Diana Yu, highlighted the extensive relationship between Guerra and Miller dating back to middle school, and up to their time living together in 2021.
Guerra testified Miller “was like a brother to me,” and described him as an “inspiration.”
During their time at college, Guerra said he got mugged, stabbed, and maced, resulting in a hand injury. After the incident, Guerra claimed, Miller helped in his rehabilitation, causing Miller to flunk out of school.
In 2019 the two moved to an apartment at the DC Wharf where they started a business, and created a friend group who loved to “socialize and party,” said Guerra.
Yu also asked Guerra about the night of Miller’s death and had the defendant demonstrate the altercation on his other attorney, Kevin Mosley. Guerra claimed he and Miller were arguing before Miller pulled out a gun, pointing it at Guerra’s head.
“It was like he was picking a spot to shoot me at,” said Guerra.
Guerra then showed how he lunged forward, causing his forearm to slam into Miller’s neck, smashing Miller’s head into a concrete pillar. They then stumbled to the ground with the gun falling out of Miller’s hand. “I wasn’t trying to hurt [Miller], I was just trying to take the gun from him,” Guerra said.
Yu then presented text messages between the defendant and a witness sent seconds after the altercation, explaining, “man come get him,” “I just beat tf out of him,” “we got in an argument,” “he pulled his gun on me cocked it and put it to my head,” “I beat the sh*t out him, get him out of here.”
The text presented by Yu was a point of contention between the prosecution and defense.
Judge Lee said he was “disturbed” and “disappointed” with the last-minute motion presented by the defense in an attempt to get these texts labeled as inadmissible hearsay, an out-of-court statement that can be presented to validate evidence. The defense sent the motion to the court at 10:27 p. m. the night before. Judge Lee asked the defense if this was “intentional,” stating the defense is not “giving the [prosecution] a fair opportunity.”
“It is not the way we should be practicing law in the superior court,” said Judge Lee.
Despite his frustration with the timing of the filing, Judge Lee determined the texts were admissible. The messages were intended to show Guerra’s actions to find help for Miller after the altercation, the judge determined.
During cross-examination, the prosecutor asked Guerra why he did not call 911 once Miller ended up on the floor. Guerra said he did not believe Miller was seriously injured at the time, and he believed his friend would wake up.
During the incident, prosecutors alleged Guerra picked up the gun Miller had dropped and placed it in Miller’s bathroom, not wanting the gun to be immediately accessible.
The prosecution questioned the order of events after the altercation, pointing out irregularities in the defense’s story. In his testimony, prosecutors noted Guerra said he sent a text to the witness first. However, in defense opening arguments, Yu claimed Guerra placed the gun in the bathroom first.
The prosecution contested that while opening arguments do not count as evidence, the order of events presented by the defense was different from what Guerra had testified.
When police arrived at the scene, Guerra initially told them that Miller had been stumbling drunk and had hit the concrete pillar in the apartment, even suggesting that Miller could be overdosing. Guerra told the prosecutor that he regretted lying to the police after the incident and that at the time he had hoped “it would all go away if Pete was okay.”
Guerra reiterated that his actions came from a place of fear rather than malice.
“I lied because I was scared,” Guerra said.
Guerra’s trial is slated to resume on June 10.
