SAN DIEGO -- The reward for information leading to the whereabouts of a missing Point Loma woman has been increased to $8,000.

San Diego County Crime Stoppers made that announcement Saturday morning. This weekend marks the five-month anniversary since 50-year-old Rosa Lisowski was last seen.

Authorities said no one has seen or heard from Rosa Lisowski since March 24. The mother of three was last seen dropping her son off at his elementary school in the Loma Portal area.

Police have focused their investigation on her estranged husband, Henry Lisowski, and even searched his home, car and boat. He has not been arrested.

Rosa Lisowski's family and friends will hand hand out fliers about the reward and case Saturday at 4 p.m. at Barons Marketplace on Point Loma Boulevard.

Rosa Lisowski's family, Crime Stoppers, and The Sund/Carrington Foundation are contributing to the reward fund.
