Mom, Kids Found Decomposing Inside Car Died Of Meth Overdose: Autopsy

Melbourne, Florida -- A 35-year-old woman killed her twin babies with drugs inside her car before taking her own life, an autopsy report revealed.

Police in Melbourne discovered Andrea Langhorst and her two 3-year-old children, Olivia Dryer and Adam Dryer, dead in a vehicle parked at the Manatee Cove apartment complex on March 20.

Langhorst had died by suicide from methamphetamine and cocaine intoxication, WPTV NewsChannel 5 reported, citing the findings of the Brevard County Medical Examiner's Office.

Both her children also died from methamphetamine overdoses, according to Law & Crime. The twins’ deaths were ruled as homicides.

Neither Adam nor Olivia had any external trauma or signs of physical abuse, a medical examiner noted.

Langhorst and her children, who were from Fort Pierce in St. Lucie County, had not been seen alive in the 11 days that preceded the discovery of their bodies.

"We were looking for [Andrea] and hadn’t heard anything from her. That was unusual for her. We wouldn’t have daily contact with her, but this was a while. She was a free spirit, smart as a whip, beautiful, but lived her life to the beat of her own [drum]. It’s just a tragedy," the twins' father, Randy Langhorst, said.

Andrea reportedly had no permanent address at the time she and her children died. She had been "living out of her car” before her suicide, Lieutenant Shaun Hill, a spokesperson for the Melbourne Police Department, said.

The mother, who also stayed at Airbnb rentals, allegedly insisted on keeping her children despite her situation.

"It was final. It was her decision. We didn't exactly approve of her lifestyle. Everything is hindsight, but I'll be kicking my [butt] for the rest of my life. All I can think about are those babies," Andrea's father said.

A GoFundMe page launched to help Andrea's surviving family members "that need grief support services" has raised $1,885 as of press time.

"This unexpected loss was a shocking tragedy, and the family is broken, all suffering from trauma and still waiting for answers," the fundraiser's description read.

Before her death, Andrea had several arrests, and she also attended a drug court, St. Lucie County court records showed.
