Dennis Wilson's bizarre death at Marina Del Rey, Pt 2

Who is Karen Perk Lamm? A control agent?

She married and divorced Robert Lamm of Columbia Records Chicago.
She twice married, and twice divorced Dennis Wilson drummer for the Beach Boys.
She boasted that she was best friends of Kitty Menendez which was untrue.

Why did she die at age 49, at the Dodd Residence of 8207 Delgany Avenue, Playa del Rey, in the house previously assigned to Columbo & Murder She Wrote actor William Windom?

Who was doping Dennis Wilson at the Santa Monica Saint John's Detox Hospital? Nadalie Wood & Dennis Wlson both moored their yachts at Marina Del Rey. The Splendor and the Harmony.

Was Eugene Landy, PhD a control agent for Brian Wilson? Why did Eugene Landy reside in Rustic Canyon adjacent to the 14400 Sunset Boulevard Will Rogers Hunting Lodge Estate---Charlie Miles Maddox Manson's residence during 1968?

This is SPY versus SPY murder, in my opinion.
