An Arkansas woman has been arrested in connection to the homicide of former state senator, state police said Friday. Rebecca Lynn O'Donnell, 48, of Pocahontas, Arkansas, is currently in custody and charges are pending, police said.
Collins-Smith's remains were found outside her home in Pocahontas on June 4. Police have not yet released how she was killed.
Collins-Smith's former communications director, Ken Yang, told CBS Little Rock affiliate KTHV O'Donnell was a friend of the late senator and had worked on her most recent campaign.
In a statement, Collins-Smith's family said they were "sickened and upset that someone so close to Linda would be involved in such a terrible, heartless crime."
Authorities have not said why they suspected O'Donnell or if they are seeking any other suspects. Yang said there will be a probable cause hearing Monday.
Collins-Smith was elected to the state House a Democrat in 2010 before she switched parties in 2011. She was elected to state Senate in 2014, but lost re-election in a GOP primary.
