Date: September 1, 2016
Victim: Greg Mulvihill, Software Engineer
Offenders: Diana Lovejoy, Fitness Trainer and Weldon McDavid, Jr., Marine Corps veteran
Location: Carlsbad, California
Circumstances: Diana Lovejoy was sweet, caring, smart and had a creative gift for writing and music, she was in the marching band in high school and extremely disciplined, she had a healthy lifestyle and good looks, she did several triathlons and was a personal fitness coach, she eventually met Greg Mulvihill, after two years of dating, the couple tied the knot, they wanted a family but Diana had several miscarriages before she finally she got pregnant, it was a difficult high risk pregnancy but she gave birth to a healthy baby boy, but when the child was two, the marriage was falling apart, Diana kicked Greg out and got a restraining order, in court documents, Diana alleged that he wished her dead, sexually molested her in his sleep, and she suspected he molested her son, Greg denied the allegations and fired back, he informed the court of what life was like with Diana who he said verbally abused and belittled him over the last several years, Greg filed for divorce in August of 2014 and the couple fought bitterly over the custody of their son, at first Greg was only allowed supervised visits but after numerous investigations by the court and law enforcement, they found no evidence of abuse, they awarded Greg 50/50 custody with Diana, Diana claimed she was fearful for their lives and started self-defense training at the range, her trainer was a former Marine, this former Marine hated bullies, he joined the USMC and after he got out, he specialized in fire arms instruction, then he met a girl named Crystal Harris (story featured on Dateline), Crystal wanted to buy a gun for protection because her husband was abusive and violent, Weldon taught her how to use a gun, even how to use it under stressful situations, one night, Crystal captured on tape her husband raping her, she played the tape for Weldon, Crystal later called the police and reported him for rape, Weldon went to her house to teach her what to do if her husband shows up, Crystal never needed to use the gun because her husband was convicted of a forcible sex crime and served more than three years in prison, she was thankful for what Weldon did for her and what he taught her, she could call him anytime and he was there for her, she moved on with her life, Weldon moved on too and a few years later, Weldon found romance, she too was someone who met him while she was at the range for self-defense training, the new girl wasn’t interested at first but we was witty and intelligent and caught her attention, she too felt empowered around Weldon, he was strong and made her feel safe, they got married and had a son, then he told her about another woman he was training at the range named Diana Lovejoy, but something with her didn’t feel right, she would text Weldon at all hours and his new wife didn’t like that and didn’t feel that it was professional, on September 1, 2016, Greg was shot by what appeared to be a sniper, detectives looked for the shooter who vanished, Greg called 911 earlier in the evening to ask for advice, he said someone wanted to meet with him, they had documents he needed for the custody battle with Diana, Greg asked if he should go, the person claimed to be a private investigator, Greg went to meet with the caller looking for the documents and they saw someone in a sniper position, they started running away but Greg was shot once, Greg’s friend called 911 and Greg survived his injuries, Greg had no idea who could do this, he didn’t think Diana had anything to do with it despite a bitter custody battle, police traced the phone call to a trac-phone, they investigated where it was purchased, and it was Diana Lovejoy, they searched for evidence in DLs home, they had enough to arrest her and bring her to the station, she denied everything, they asked her if she hired someone to kill Greg and she denied it, she described her relationship with her self defense trainer, Weldon McDavid, Diana told police Weldon was going to scare Greg into dropping the custody battle and go away, she paid him to scare him, on Sept 1, he got into her car with his gun and she dropped him off at the location, he said things went wrong and he had to shoot him, she said she hired him to intimidate him only, Weldon’s home was searched for guns and the police found a portion of an AR-15 in the garage, there were 7 spent shell casings, the same number of shots fired that night, police arrested Weldon and initially he denied everything, police believe DL fabricated the abuse allegations against Greg, DL used Weldon to carry this murder out, she slept with him and used her sexuality to manipulate Weldon, the two faced trial together, Weldon admitted to being at the scene of the shooting, Diana admitted to hiring Weldon to intimidate him, the prosecutor confronted DLs false allegations against Greg in the trial, DL asked her aunt to find a hitman, she refused and DL found Weldon, Weldon testified on his own behalf that he was hired by DL, he said he wasn’t planning on firing any shots, he thought he heard one of them say they had a gun, he said he did not aim at Greg to kill him, lawyer said he had misguided hero complex, DL picked the night of the new moon when it was the most dark out, Weldon said he was just trying to help DL and her son, DL said she didn’t have any control over Weldon’s actions
Disposition: Diana Lovejoy was found guilty of attempted murder and conspiracy to commit murder, she was sentenced to 26 years to life in prison; Weldon McDavid, Jr. was found guilty of attempted murder and conspiracy, he was sentenced to 50 years to life in prison
