Her Last Call

Episode of 20/20 · June 20, 2026 · 1 h 27 min

20/20 revisits the 2008 abduction and murder of Florida mother Denise Amber Lee, the 911 failures, Michael King's trial, and his 2026 execution.

Summary

This 20/20 episode, anchored by Deborah Roberts, recounted the January 17, 2008 abduction of 21-year-old Denise Amber Lee from her North Port, Florida home. Her husband Nathan Lee described coming home to find their two young sons alone and calling 911, while her father, Charlotte County detective Rick Goff, and North Port investigator Chris Morales described the rapid multi-agency search and a neighbor's sighting of a green Camaro.

The program focused on a series of 911 calls: Denise's own call from her abductor's phone, which led police to Michael King; a call from Sabrina Muxlow relaying that King's cousin Harold Muxlow had seen a tied-up woman and lent King a shovel and gas can; and motorist Jane Kowalski's call describing screaming from a Camaro. Kowalski's call went to Charlotte County dispatch and was never broadcast to searchers. A trooper later stopped King without Denise; her body was found buried in woods after a canine search.

Family members argued the Kowalski call could have saved Denise, while the sheriff at the time disputed that. King was convicted of first-degree murder and sentenced to death; the family settled a wrongful death suit for $1.2 million and pushed the Denise Amber Lee Act mandating dispatcher training. The episode closed with King's execution on March 17, 2026, and reflections from Denise's now-grown sons.
