ARLINGTON, Tenn. — “A man came over beating on the door across the street,” Jason Woolbright said.

Neighbors claimed they saw Jonathan Todd on Saturday and heard him screaming from a neighborhood in Arlington.

“You hear angry voices,” Jennifer Lester recalled.

Todd is accused of threatening an undercover Shelby County Sheriff’s Office detective and his family.

“Much more if you’re going to come to a police officer’s house and threaten him and his family. That’s frightening,” Lester said.

Deputies said the incident stemmed from a drug complaint involving Todd’s 11-year-old son.

Court documents showed Todd said his son was innocent and traumatized by detectives showing up to his house.

Todd reportedly yelled, “Your family is about to feel the same way my family feels.”

“It does speak to just how dangerous this profession is,” SCSO spokesman Chip Washington said. “Obviously it was a bit unnerving to have a suspect come to your house and make threats to you and your family.”

Neighbors found it unnerving how Todd even found the undercover detective in the first place.

“A suspect can find out where he lives,” Woolbright said. “That’s really dangerous in my opinion.”

Washington said the SCSO is looking into that but could not release many details in the investigation.
