While for the gunmen who and wounded three others early Sunday, city officials are wondering whether any businesses should be held responsible for the party that preceded the shootings.
At a city council meeting Monday night San Leandro Police Chief Sandra Spagnoli said the party was held in Suite 22 of the industrial park at 2661 Alvarado St.
That warehouse is leased to C&M Trailer Rentals.
But Damon McKinney, owner of C&M Trailer Rentals, told Patch on two occasions that he did not rent out his warehouse for the Saturday night party.
"It was not my shop," he said.
Several council members wondered aloud Monday night whether the business that did rent out the space for the party could be held liable in any way.
But it was too early to get answers.
At a press conference Monday, police department spokesman Sergeant Doug Calcagno said police have only just begun to sit down with city officials to consider potential business liability.
In the larger sense, city officials aren't sure how to regulate large parties, organized by promoters, like the one that preceded the shootings.
On the one hand, occur frequently.
On the other hand, Spagnoli suggested that police are already stretched too thin, especially on weekends, to check on party permits.
"The larger issue is that these are underground parties and they are not going to get permits," said San Leandro Police Captain Pete Ballew. "If you ask their promoters about permits they just go elsewhere."
He suggested some spot underground party promoters who want to rent space. One tip: be suspicious of someone who offers to pay in all cash.
In a related development, San Leandro police say they want to talk to , promoter of the party that brought an estimated 200 people to the San Leandro warehouse.
Calcagno said Edwards didn't get a permit for that party but it isn't clear he needed one under the city's rules.
Meanwhile, C&M is likely to remain under scrutiny.
On its website the company says it will be "hosting upcoming community events such as 'bike nite' and 'muscle car nite' once a month."
One Patch reader spotted a C&M note on Facebook inviting people to a Mayweather fight party in September. It had a $15 entry charge. Attendees were advised to bring their own alcohol.
"Music and club atmosphere afterward," the note continued. "We partyn till 2am."
