The development director for a longtime Jacksonville residential community for adults with developmental disabilities and her 30-year-old daughter were the victims of Wednesday's murder-suicide by her ex-husband at a Beach Boulevard condominium, according to the Jacksonville Sheriff's Office.

Lori Elizabeth Rush was killed with daughter Elizabeth Christine Ceratt by former husband Alan Junior Rush, according to police.

Lori Rush had worked in the Catholic Diocese of St. Augustine for a number of years through 2011, helping with the formation of the Guardian Catholic Schools at Holy Rosary and St. Pius V Catholic Churches on the city's Northside, diocesan spokesman Brandon Duncan said. The 52-year-old woman, also an active volunteer at Blessed Trinity Catholic Church, then moved to the non-diocesan L'Arche Harbor House on Arlington Road.

"We are very devastated at the loss and we know the L'Arche community is devastated for the loss of Lori as well," Duncan said. "She worked there for a number of years and did a lot of wonderful work. She was also a great supporter for the Guardian Schools and did a lot of wonderful work to get that started."

Ceratt's husband, Louis Ceratt, posted that he was "feeling heartbroken" on his Facebook page late Wednesday, along with "Hold your loved one close. You never know what can happen." Family member Emily Rush posted a sad farewell at the same time as she asked how does anyone know if your last opportunity to speak to someone will be the last chance?

"The answer is, you won't! Make every conversation and moment count!!" she wrote. "I can't believe the circumstances and I don't know if it will ever settle with me, but rest in paradise nana and papa."

Police were called to the Monterey Condominiums at 12171 Beach Blvd. at 3:40 p.m. on a report of shots fired, then found the three dead inside one of the homes, Sgt. Chuck Ford said. The gated community is just west of Kernan Boulevard.

Police now say Alan Rush, 60, arrived at his estranged wife's home and shot her. He encountered his step-daughter, who had come by to check on her mother, and shot her, police said. Rush then called 911 and said two people had been shot. He was also found dead from a self-inflicted gunshot wound when officers arrived.

No details have been released as to what may have led up to the shootings. Duval County court records show no arrests or injunctions between the estranged couple.

Rush was well-known for her work at L'Arche Harbor House next to Christ the King Catholic Church. The facility has operated there for almost 30 years, one of 147 faith-based communities in 35 countries. Early Thursday, administrators there said they were awaiting more news on Rush's death but are praying for the family.

Blessed Trinity Catholic Church is only three miles from Rush's condominium, where Mrs. Rush was a former head of its Council of Catholic Women.
