LOS ANGELES -- The head of security at Dodgers Stadium is retiring and will be replaced by a former Los Angeles Police deputy chief.

The Dodgers said Sunday that Rich Wemmer's last day will be Thursday, and Michael Hillman will oversee security at the stadium for the rest of the 2012 season.

Wemmer took the job in April 2011 after security became an issue when San Francisco Giants fan Bryan Stow was severely beaten in the stadium parking lot. Wemmer, who retired from the LAPD in 2008 after nearly 40 years in law enforcement, said he had been planning for his retirement for quite some time.

Dodger President Stan Kasten said he believes the team's ongoing efforts to provide a safe, family-friendly environment to its fans will be in good hands with Hillman.
