Timothy O’Brien faces a July 13 preliminary hearing in the death of Lauren Jensen-Green.
COLORADO SPRINGS, Colo. — Prosecutors are preparing to present evidence Monday against Timothy O’Brien, a 60-year-old man accused of killing Lauren Jensen-Green and concealing her body inside a motel room before leaving the South Nevada Avenue property.
The July 13 preliminary hearing will be the first major test of a case based on O’Brien’s alleged confession, an earlier statement to a roommate and physical evidence found around Jensen-Green’s body. A judge will decide whether probable cause supports the first-degree murder charge. The hearing will not decide guilt, and O’Brien retains the presumption of innocence.
At a preliminary hearing, prosecutors generally present enough evidence to show that a crime probably occurred and that the accused person probably committed it. The standard is lower than the proof beyond a reasonable doubt required for conviction at trial. In O’Brien’s case, the state may rely on a lead detective rather than calling every motel worker, officer and forensic specialist. That detective could summarize reports, describe the room and recount statements attributed to O’Brien. Defense attorneys may question the witness about missing evidence, inconsistent accounts and police procedures. The judge could allow the first-degree murder case to continue, determine that a different charge is better supported or make other rulings permitted under Colorado procedure. Even if the charge moves forward, O’Brien will have additional opportunities to challenge evidence. The court may also address future deadlines, detention conditions and the schedule for later appearances.
The most direct prosecution evidence appears to be O’Brien’s own reported description of the killing. Police say he told a homicide detective that he and Jensen-Green, 65, met on a bus and went to a motel in the 1700 block of South Nevada Avenue. They checked in May 18 and used methamphetamine during the stay, according to his account. O’Brien allegedly said Jensen-Green became loud and continued “ranting and raving” while he was trying to rest. “I was actually just trying to lay there and enjoy my high,” he reportedly told the detective. He said he “snapped,” removed a hammer from his backpack and struck Jensen-Green several times while she was lying down. Investigators say he then held a pillow over her face to “finish it.” Prosecutors may argue that those details demonstrate an intentional killing rather than an accident or unplanned struggle.
The defense is likely to examine how police obtained the statement and whether it accurately reflects O’Brien’s words. Public reports do not say when detectives advised him of his right to remain silent, whether he requested an attorney or whether the complete interview was recorded. O’Brien’s admitted drug use may also become relevant to his memory and ability to understand questioning, although intoxication does not automatically make a statement inadmissible. His lawyers could ask whether detectives used leading questions, whether officers omitted qualifications from the affidavit or whether O’Brien supplied facts that only the killer would know. Prosecutors may respond with recordings, signed documents or testimony showing that he spoke voluntarily. A suppression motion, if filed later, would require a separate legal review. The preliminary hearing judge may hear only a limited account of the interview rather than deciding every constitutional issue surrounding it.
O’Brien allegedly made other statements before the formal interrogation. His roommate told police that O’Brien had admitted killing a woman but claimed she came toward him with a knife. That description differs from the account in which he attacked because Jensen-Green was yelling. Police have not announced finding a knife in the room. They also have not released autopsy details that might show whether Jensen-Green or O’Brien had injuries associated with a struggle. Prosecutors could use the conflicting stories to argue that the self-defense claim was invented and later abandoned. The defense may challenge the roommate’s memory, motive or wording. Because the roommate has not been publicly identified, little is known about the circumstances of the conversation. The hearing may reveal when it occurred, what O’Brien allegedly said and how the witness directed police to the correct motel.
Officers entered the room at about 11:35 a.m. May 20 after being sent to the property for an urgent assist. They found blood on the walls, bedding and floor, according to arrest records. Jensen-Green’s body was wedged between a bed and a nightstand and was unclothed from the waist down. Wet rags bearing apparent blood were found in the bathroom. Investigators believe the rags may indicate an attempted cleanup, though laboratory findings have not been publicly released. Police also have not said whether they recovered the hammer or pillow O’Brien allegedly described. The presence or absence of those items could affect how closely his statement matches the scene. Evidence technicians may have collected fingerprints, DNA, fibers, photographs and samples from the room, but authorities have not published a complete inventory. The prosecution needs only probable cause at Monday’s hearing, while the full forensic record would become more important during trial preparation.
Another part of the case concerns what O’Brien allegedly did after Jensen-Green died. Police say he moved her body into the gap beside the bed so it would not be immediately visible. He remained at the motel long enough to speak with housekeeping the next morning and said Jensen-Green was asleep, according to the records. “I didn’t want her discovered until it was time for checkout on the second day,” he allegedly told detectives. “I figured it gave me time to get away.” Prosecutors could present the alleged concealment, cleanup and warning to housekeeping as evidence of consciousness of guilt. Defense lawyers may argue that later conduct does not establish the state of mind required at the moment of the killing. Motel employees and business records could clarify the checkout schedule, O’Brien’s departure and whether he took any steps to change or extend the reservation.
Police did not arrest O’Brien until May 25. Officers encountered him at a Maverik gas station and said he initially identified himself as “Mark.” A law enforcement database check confirmed who he was, and he was detained on an unrelated warrant. O’Brien had bandages on his hands and fingers. He reportedly said he had fallen down an incline and suffered scrapes. Authorities have not revealed whether the injuries were photographed, medically evaluated or connected to evidence in the motel room. At a hospital, officers collected DNA. O’Brien allegedly brought up the homicide without a direct question and denied sexual contact with Jensen-Green. Police say he objected to being accused of conduct he claimed did not occur while distinguishing it from “something I did.” Prosecutors may treat the remarks as admissions. The defense may dispute their meaning or seek to exclude them.
The condition of Jensen-Green’s clothing and O’Brien’s reported hospital remarks have created questions that police have not publicly answered. Authorities have not charged him with sexual assault in connection with her death. They have not released sexual-assault examination results or explained why investigators sought particular biological samples. An absence of a separate charge does not by itself establish what happened, and the reported court documents do not provide a complete forensic account. The judge may not need to address those matters to decide whether probable cause supports murder. Still, the issue could influence what evidence prosecutors disclose and what expert analysis the defense requests. Both sides may seek laboratory records, autopsy photographs and reports documenting how investigators handled the scene. Any disputed evidence would be subject to courtroom rules before a jury could consider it.
O’Brien was reported to be held in the El Paso County jail on a $50,000 bond after his first appearance. The court could revisit his detention as the prosecution develops. He also faces kidnapping and aggravated robbery accusations in another criminal case. Those allegations remain separate and cannot substitute for proof in Jensen-Green’s death. Reports found a publicly available 1992 arson conviction in his background, but an older conviction does not establish guilt in a new case. Judges closely control whether juries hear evidence of unrelated conduct because of the risk of unfair prejudice. The state must build the homicide prosecution from the motel evidence, witness accounts and admissible statements. O’Brien’s attorneys can demand disclosure of favorable evidence and challenge attempts to introduce information that does not properly belong in the case.
The first-degree murder charge carries severe consequences, but the precise punishment would matter only after a conviction. Before any trial, prosecutors must file formal pleadings, disclose evidence and respond to defense motions. Lawyers may seek hearings over the interrogation, searches, DNA collection and witness identification. Experts could evaluate blood patterns, injuries, toxicology or mental condition. The court may set deadlines for those reviews after the preliminary hearing. A trial date has not been announced, and no public report has identified plea negotiations. If the judge finds probable cause, the case would advance toward arraignment and further pretrial proceedings. O’Brien could enter a plea, and attorneys would begin narrowing which evidence a jury may hear. If probable cause is not found on the charge as presented, prosecutors may have other procedural options depending on the ruling.
Jensen-Green’s family has remained largely outside the public legal debate. Relatives provided police with a photograph that they said showed how they wanted her remembered. Little else has been released about her background, her relationship with O’Brien or why she was staying at the motel. The El Paso County Coroner’s Office identified her after the body was found, and police counted her death as Colorado Springs’ sixth homicide of 2026. At the comparable point in 2025, the city had recorded 16 homicides. That year-to-year figure may appear in official public-safety reports, but Monday’s hearing will focus on the evidence surrounding one death. Jensen-Green’s family may attend future proceedings or make statements later, though no appearance has been announced.
The July 13 hearing is expected to organize a case that has so far emerged through police summaries and arrest documents. It may establish which statements, witnesses and physical findings prosecutors consider essential. Whatever the ruling, the proceeding will mark an early stage rather than a final judgment in Jensen-Green’s death.
