Brent Adam Adler, 33, was killed during a violent home invasion on May 11, 2016, at his home in the Lake Murray area, in the 8500 block of Tommy Drive. Up to five males forced their way into the residence; one of the intruders was armed with a handgun. The intruders began issuing commands to the occupants, and Adler resisted while trying to protect himself and others. He was shot at least once in the upper body and was later found in the driveway of his home.

Witnesses described several suspects, including a white male about 25 to 30 years old with blond hair wearing a yellow-checkered shirt. A green Ford Expedition was seen leaving the area, though it was unclear whether that vehicle was involved. The San Diego Police Department Homicide Unit investigated the case; the initial inquiry did not immediately produce arrests.

Anyone with information about the invasion, the suspects described, or the green Ford Expedition is asked to come forward.
