California man finds out ex is pregnant with new man’s baby then sneaks under garage door and her say police

The agreement spared Vaughn Boatner a murder trial after prosecutors initially pursued far more severe charges tied to the 2023 shooting.

OAKLAND, Calif. — A homicide case that once carried murder allegations, child abuse allegations and major gun enhancements ended with Vaughn Boatner receiving a 35-year prison sentence after pleading no contest to voluntary manslaughter and attempted murder.

The shift in charges matters because it changed both the legal stakes and the public picture of the case. Early filings and news reports described a prosecution built around the fatal shooting of Monique Aldridge, the wounding of her boyfriend and the presence of the former couple’s 5-year-old son inside the home. The later plea agreement, reported after sentencing, removed the prospect of a jury verdict on murder and left many of the most contested details preserved mainly in police statements, warrants and hearing testimony.

At the start, prosecutors were signaling a much harder case posture. CBS Bay Area reported in 2023 that Boatner faced first-degree murder and attempted premeditated murder exposure, along with gun enhancements that could have pushed punishment far above the sentence he ultimately received. ABC7 and KTVU reported that after his arrest he was booked on homicide, attempted homicide, child endangerment and firearm-related allegations. Hayward police said officers responding to Cassia Drive on May 11, 2023, found Aldridge and a second victim shot inside the residence and a 5-year-old child unharmed in the home. Those first public accounts established the seriousness of the allegations long before any plea deal narrowed them.

The factual record that followed was severe. Police identified Aldridge as the person who died and described the second victim as a boyfriend who survived after being taken to a hospital. KTVU later reported, citing a probable cause warrant, that Aldridge had been shot in the head seven times and was in the early stages of pregnancy. Law&Crime’s later report on the case said Aldridge had only recently learned she was pregnant with the surviving boyfriend’s child. That report also summarized testimony from a preliminary hearing in which the boyfriend said Boatner slid under a partially open garage door and attacked. According to that testimony, the couple’s young son was nearby watching “A Minecraft Movie,” and the boyfriend rushed him to safety after the gunfire began.

Because the case did not proceed to trial on the original murder count, the public record is uneven in places. There is no jury verdict explaining which version of the encounter jurors accepted, and the materials reviewed do not include a full sentencing memorandum or a detailed public statement from Boatner laying out his account. Even so, the procedural path is clear. Police said they identified him within hours, obtained arrest and search warrants and warned that he was armed and dangerous after failing to find him at his residence. The U.S. Marshals Service later offered a reward for information leading to his arrest. Boatner was captured in Seattle on May 22, 2023, with the help of federal and local law enforcement agencies, ending an 11-day search.

The plea changed what the court had to decide next. Instead of litigating guilt on murder before a jury, the case moved to sentencing on the negotiated counts. Law&Crime reported that Boatner, now 36, pleaded no contest to voluntary manslaughter and attempted murder and that murder and child abuse charges were dropped under the deal. He was sentenced March 19 and was awaiting transfer to state prison. Public reporting did not fully describe whether any restitution, protective orders or other collateral issues remained pending after sentencing. In practical terms, though, the main open question of criminal liability had been resolved by agreement rather than verdict.

Outside the courtroom, the case continued to be defined by the people left behind. Aldridge’s uncle, Lorenzo Smith, called the killing senseless soon after it happened and said the family faced the task of explaining the loss to the boy she shared with Boatner. The surviving boyfriend’s testimony also carried lasting weight because it linked the domestic timeline, the garage attack and the child’s immediate reaction in a single account. A negotiated sentence can settle charges. It does not settle the emotional record that remains attached to them.

Boatner’s case now stands as a concluded prosecution unless post-judgment litigation emerges. The next visible development would most likely be an appeal notice, prison transfer record or any later restitution-related hearing.
