JAKARTA, Indonesia (AP) — More families of victims of the Lion Air crash in Indonesia are suing Boeing Co. after its chief executive apologized last week and said a software update for the MAX 8 jet would prevent further disasters.

Family members and lawyers said Monday that CEO Dennis Muilenburg's comment related to an automated flight system in a video statement last week was an admission that helps their cases.

The anti-stall system is suspected as a cause of the Lion Air crash in December and an Ethiopian Airlines crash in March, which together killed 346 people.

Families of 11 Lion Air victims said at a news conference they are joining dozens of other families in filing lawsuits against Boeing.
