DOVER — The case of a 39-year-old Dover man charged after an alleged April 2014 home invasion involving a senior citizen will not be further prosecuted, officials said this week.

Timothy L. Safford was scheduled for trial on Monday in Kent County Superior Court on kidnapping, robbery, weapons and assault-related charges regarding an incident in the 700 block of Halsey Road in Dover, but the case was not prosecuted “in the interest of justice,” according to the Delaware Attorney General’s office.

Shirley Smith

On Sept. 9, 2014, co-defendant Shirley Smith was sentenced by Judge Robert B. Young to 22 years in prison after an 82-year-old man allegedly was robbed and assaulted at his home several months earlier, authorities said.

Smith earlier pleaded guilty to home invasion, first-degree assault, possession of a deadly weapon during the commission of a felony and second-degree conspiracy, officials said. She was 33 at the time of her arrest, police said.

According to the AG’s office, Smith’s sentencing included:

• Home invasion, Level 5 for 25 years suspended after serving 15 years followed by one year Level 4 work release followed by one year Level 3 probation.

• First-degree assault, Level 5 for 25 years suspended after serving five years followed by one year Level 3 probation.

• Possession of a deadly weapon during the commission of a felony, Level 5 for two years.

• Second-degree conspiracy, Level 5 for two years suspended for one year Level 3.

At the time of the incident, police said a man was stabbed numerous times in the back and torso area and tied up for nearly seven hours before getting free and calling 911. His bank card and vehicle also allegedly were taken, authorities said.

Police said the man was treated at Bayhealth-Kent County Hospital in Dover and expected to fully recover from his injuries.

Authorities said that Smith was reportedly an acquaintance of the wounded man.

Attorney Adam Windett was listed in court records as representing Mr. Safford, with Jason Cohee prosecuting for the state.

A Dover Police dispatcher was later named civilian of the year after taking a 911 call from the elderly victim, and then quickly notifying officers the next day when a suspect was seen at a convenience store. The suspect was arrested without incident soon afterward, police said.
