A tragic boat capsizing near Alcatraz Island in San Francisco Bay has left one person dead and three missing, prompting a massive multi-agency search. Senior correspondent Claudia Cowan reports live, detailing how the 49-foot cabin cruiser was carrying 20 adults for a memorial service when it overturned due to rough seas. Authorities are investigating the exact cause, with recovery efforts ongoing in the frigid waters.

A 59-year-old New Jersey mother was allegedly drunk at the helm when her boat slammed into a channel marker on Memorial Day, killing her 28-year-old son.

Jennifer L. Pearson, 59, is charged with death by vessel, a second-degree offense; operating a vessel under the influence; reckless operation of a vessel; operating a vessel without a Boating Safety Certificate; and failure to have a proper lookout, according to a New Jersey State Police news release.

On Memorial Day at around 5:45 p.m., Pearson was boating in Barnegat Bay near the Brant Beach Yacht Club in Long Beach when she allegedly smashed her 23-foot center console into the marker sending her son, Gunnar Pearson, 28, and his girlfriend flying into the water, according to charging documents obtained by NJ101.5.
