In the realm of criminal psychology, a question persists: Can one truly spot an individual capable of committing a fatal crime? After decades of experience, experts conclude that while the answer is complex, a specific psychological profile—the destructive narcissist—often leaves a deadly pattern of manipulation and emotional wreckage.

This analysis examines three devastating American true crime cases where unchecked narcissistic control and pathological lying led to the ultimate betrayal: the unlawful taking of a human life.

Case 1: Tasha Fields and the Custody Battle Scheme

In Florida, Dwayne Barrentine fell under the spell of the attractive, smooth-talking Tasha Fields, a woman who promised the perfect recipe for a blended family. Tasha showered Dwayne with love notes and doted on his son, presenting herself as a devoted single mother seeking stability.

However, Dwayne’s first glimpse of the “real Tasha” came through letters addressed to multiple aliases: Tasha Fields, Tasha Morton, Tasha Kemp, Tasha Hesse. He discovered she had been married five times by the age of 31—a staggering pattern of relationships she later tried to justify with tears.

The layers of Tasha’s pathological lies were endless: she falsely claimed a bachelor’s degree, a federal judge as a grandfather, and fabricated elaborate stories instantly. Pathological liars like Tasha create a false reality to cloak their conscience, believing their lies are superior to the truth.

Dwayne’s digging exposed more disturbing secrets: Tasha had abandoned two other children by different fathers.

The ultimate bombshell was dropped by an ex-boyfriend, who mentioned Tasha was involved in the unlawful taking of an ex-lover’s life. Dwayne soon discovered that Mitch Kemp, Tasha’s ex-husband, had vanished in the middle of a custody battle for their young daughter.

Dwayne reported his suspicions, and police investigation quickly confirmed his fears: they had a fatal assault on their hands.

Tasha had eliminated Mitch Kemp by manipulating her fourth husband, Greg Morton, into confronting him. She used the most profound form of emotional coercion, lying that Mitch had committed an assault on intimacy against her.

Greg, believing he was defending his wife’s honor, ambushed Mitch Kemp at the farm. Greg testified that Mitch put his hands up, but Greg fired five projectile rounds into his chest.

Mitch fell, bleeding, and reached toward Tasha, who shockingly kicked his hand away and spat in his face, commanding Greg to finish the act.

Tasha Fields, a narcissist to the end, was convicted of the premeditated unlawful taking of life and sentenced to life imprisonment without the chance of parole. Greg Morton received 19 years for a lesser charge, a victim of his own misplaced love for a master manipulator.

Case 2: Danny Pelosi and the Alternative Reality

In New York, former FBI profilers encountered another classic case of narcissistic delusion: Danny Pelosi, an electrician convicted of the unlawful taking of wealthy Wall Street mogul Ted Ammon‘s life.

Pelosi was hired by Ted’s estranged wife, Generosa Ammon, and quickly became her lover. Generosa was going through a contentious divorce, and Ted was later found fatally assaulted.

Pelosi, serving 25 years to life, claimed he was innocent. He wove an elaborate, ever-changing series of lies, insisting Generosa had organized three other men to commit the fatal assault.

His most shocking claim was that the fatal assault was captured on a home security hard drive. Pelosi insisted he watched the fatal assault on his laptop, claiming: “I’ve seen him get killed on the freaking computer.”

Pelosi’s account was full of conflicting details—different times, different weapons (claiming Ted was assaulted with three different projectile weapons). This pathological lying is characteristic of a narcissist: if reality does not fit their dream, they create their own.

When confronted with the logical flaw—that the hard drive would exonerate him—Pelosi claimed he had thrown the crucial “black box” into a creek to protect Generosa and the accomplices.

Pelosi’s testimony was dismissed as the alternative universe of a classic narcissist obsessed with control. He never produced the so-called evidence because, investigators concluded, it simply did not exist. He was convicted of the unlawful taking of Ted Ammon’s life, a judgment he continues to reject from behind bars.

Case 3: Kim Coleman and the Voicemail Rage

In Louisiana, the case of Kim Coleman and Air Force Sergeant Brian Spinks demonstrated the extreme danger of a narcissist scorned. Kim, a popular girl used to being the center of attention, quickly became obsessively jealous of Brian.

Narcissists thrive on admiration, and any lack of attention is perceived as a profound insult. Kim constantly monitored Brian’s phone and demanded his undivided focus.

Brian, tired of the controlling jealousy, began to deliberately avoid her. When they encountered each other at a bar, the situation became volatile. Kim was yelling and screaming, demonstrating the constant defensive posture of a narcissist protecting their emotional territory.

The breaking point came when Brian, seeking a clean break, en@ded the relationship via voicemail.

The perceived rejection sent Kim over an emotional cliff. On January 17, 2010, she snapped, arriving at Brian’s door seeking the ultimate revenge.

Kim viciously assaulted Brian, inflicting over 60 wounds in a frenzy of rage that witnesses described as “demon-like.”

In a desperate attempt to lie her way out of the crime, Kim called 911, blaming the assault on a mystery intruder. Her attempt at deception failed immediately: Brian’s weak pleas for help could be clearly heard in the background of her 911 recording.

The recording became irrefutable evidence, capturing Brian’s final moments of life and exposing Kim’s callous pretense.

Kim was convicted of the unlawful taking of life and sentenced to life in prison without parole. Her lack of defensive wounds confirmed her role as the aggressor.

These three cases underscore a vital warning: if a relationship is characterized by pathological lying, intense jealousy, resentment, and a profound need for control, it is a deadly pattern. The only way to survive a narcissist is to leave—before their distorted reality consumes your own life.
