Police said she met in Brooklyn with an undercover investigator posing as a hitman to discuss an alleged plan to have her husband run over by a car after the couple had lunch together on Sunday.

Sava-Adams allegedly gave the undercover officer a photo of her husband, along with jewelry and a stamp collection valued at $60,000, according to the NYPD. The "hitman" was to flee the scene after the he ran over her husband with his car, police said.

Sava-Adams was arrested when she left the officer's vehicle on Thursday, police said.

She is charged with first-degree conspiracy and second-degree criminal solicitation, according to court documents.
