Former SMPD sergeant writes book


Former San Marcos Police Department (SMPD) Sergeant and San Marcos Area Recovery Team (SMART) founder Dan Misiaszek has written a book, Hardened Hearts, about his 30 years of public service, much of it in San Marcos.

Some area residents may remember Misiaszek as the diver who set the world’s record for the longest freshwater dive (60 hours and 24 minutes), which he accomplished at Aquarena Springs in 2001. His record-breaking submergence was recorded in the 2003 Guiness Book Of World Records. The dive was done as a fundraiser for SMART. Video of his dive can be found at

He garnered area fame as a search and rescue diver who explored the rocky mysteries of Jacob’s Well. He is equally well-known for his rescue of a a 16-year-old boy who was trapped in Cummings Dam.

In the book, Misiaszek chronicles his various public service careers as paramedic, police officer, firefighter, army soldier and search and rescue diver. He recounts his time as a police officer in San Marcos and relates incidents from his stint with Blackwater (now known as Xe) as a diplomatic security contractor. He comments  in his press release, “There are even some surprises in the book that may shock you.”

Hardened Hearts is available at or directly from the publisher Amethyst Moon at

  1. I have read this book. It is well written, very descriptive with interesting insider information and heart stopping action. In some of the situations, even though you know that the author survived to write this book, you are breathless with fear for his life. He has captured the feeling of “being there” which is the epitome of non-fiction writing. I bought several copies to give to friends and family. Great Christmas presents. It wouldn’t surprise me at all for this book to show up on The New York Times Best Seller List. “A great read.”
