Just got off the phone with Dave Demerjian, head of the district attorney’s Public Integrity Division.

He said a lingering case investigating alleged campaign finance violations by La Puente Mayor Louie Lujan is still ongoing.

No charges have been filed yet.

“We’re still working it,” Demerjian said.

Last we heard, a grand jury was supposed to be held in August and former water board member Leon Garcia was subpoenaed to attend.

We never heard back from Garcia about whether or not it actually happened, and Demerjian can’t confirm grand jury proceedings until — or if — criminal charges are filed.

Meanwhile, you could follow Louie on Twitter — except he hasn’t tweeted yet.
