Incident
Deputy Sheriff Mark Kemp died as the result of complications from being exposed to dangerous chemicals during the investigation of a meth lab in 1990.
Immediately following the initial exposure Deputy Kemp began to suffer from severe asthma attacks. The attacks persisted and he was hospitalized several times. On November 9, 1994, he was attending a training class when he suffered a severe asthma attack. He was transported to a local hospital where he passed away.
Deputy Kemp had served with the Riverside County Sheriff's Department for 10 years.
The 9th marked 30 years since that fateful day when you left us all. I remember the sadness and shock on the day you passed. You have not and will never be forgotten. Rest in peace Mark.
