MYSTERIOUS DEATH OF: Laura Sweetman

The gist

Laura Sweetman, a accomplished pediatric neurologist, was discovered dead in her bathtub on December 9, 2013, with an undetermined cause of death. Though multiple people close to her—including her father, friends, and coworkers—suspected her abusive estranged husband Dave Sweetman of involvement, Gilbert Police Department conducted minimal investigation and closed the case within months. The episode reveals systemic failures in both the police investigation and the medical examiner's office, leaving Laura's death a complete mystery after 12 years.

Key takeaways

• Laura discovered Dave's affair in April 2013: She found out Dave had fathered a preschool-aged child with another woman while married, prompting her to plan an immediate divorce and separate living arrangement.

• Domestic violence incident on April 21, 2013: Dave allegedly choked Laura three times and held her against her will; she called police from a movie theater. Though she had an audio recording of the incident, charges were dropped due to "insufficient evidence," though she obtained a protective order and full custody.

• Suspicious surveillance in November 2013: A neighbor reported a white Isuzu Rodeo parked across from Laura's rental house with a white male driver; the vehicle later appeared in her driveway. The neighbor provided police with the license plate number, but there's no evidence police ever followed up on this tip.

• Multiple romantic interests in December 2013: In the week before her death, Laura texted at least five different men trying to make plans. Will, a gym trainer she'd been seeing, admitted to being at her house "maybe an hour" on December 8, but police never asked what time he left or what they were doing.

• Medical examiner Dr. Mark Shelley had a serious ethical violation: In 2011, while working as a military medical examiner in Virginia, Shelley took a deceased marine's brain home, removed it from a specimen jar, and let his children feel it while his wife took pictures. He was reprimanded with a $2,500 fine and suspended, but then moved to Arizona and was hired by Maricopa County before facing potential termination.

• Toxicology director Norman Wade had a concealed felony: Wade was convicted of grand theft of a firearm in 1995 (selling evidence to a pawnshop) but was hired by Maricopa County in 1994 during his investigation. When reapplying as lab director in 1999, he falsely claimed no criminal convictions; he was hired anyway and testified in major cases for two decades before retiring in 2016 to avoid investigation.

• Autopsy findings are contradictory and concerning: Laura had bruises consistent with drowning but also head contusions; foaming at the mouth suggested drowning, yet the ME noted "no definitive evidence of drowning." A stimulant prescription was found at the scene but nothing was in her toxicology. Her medical history listed a prior heart attack, but the autopsy showed no cardiac scarring—contradicting the diagnosis.

• Investigation was minimal and unprofessional: Police conducted only brief phone interviews (Emily's lasted 10 minutes with no follow-up), never interviewed four of the five men Laura contacted that week, never searched their phones or obtained alibis, and never followed up on the suspicious vehicle tip. The case was closed in September 2014 without meaningful investigation.

Notable quotes

• Emily on Laura's state of mind: "Laura was always scared of Dave, and she did not feel safe."

• Dr. Shelley describing showing his children the brain: "I allowed them to gently feel the brain while wearing plastic mittens. I emphasized respect for the decedent the entire time."

• Gilbert Police Department's response to the medical examiner shortage: "No employee is perfect. We do not expect perfect pasts."
