Police believe that the suspect connected to the brutal murders of a wealthy family in Washington, D.C., on May 14 did not act alone.

Investigators say that Darron Dellon Dennis Wint, who goes by the alias Daron Dylon Wint, worked with accomplices to kill Savvas Savopoulos, a wealthy manufacturing executive, along with his wife, Amy, their 10-year-old son Philip and the family's housekeeper, Veralicia Figueroa. Officials used DNA evidence to link the 34-year-old suspect to the crime scene.

According to an affidavit seeking an arrest warrant for Wint, a city detective said he believed that Wint had help from other people in holding the three adults and child hostage before killing them and setting the family's home on fire, reports NBC News.

The crime "required the presence and assistance of more than one person," reads the criminal complaint.

D.C. Police Chief Cathy Lanier also commented, saying, "It's pretty obvious that there was coordination.

"Whether there was someone else that actually took part in the kidnapping and the murder, it's going to take time to get this evidence together, and we just don't want to jump to conclusions or draw conclusions too soon."

However, so far no one else has been charged in connection to the murders.

On Friday, the 34-year-old suspect appeared before a District of Columbia judge to face charges of first-degree murder.

The Savopoulos family and their housekeeper were found dead on May 14 in their home, which is located in the same neighborhood where Vice President Joe Biden lives. Authorities say Wint entered the home sometime around 6 p.m. on May 13 and then held the four people hostage overnight before they were killed on May 14. After setting the family's $5 million mansion on fire, he escaped with $40,000 in cash.

According to D.C. Police Chief Cathy Lanier, the killings were likely "not a random crime," reports Fox News. It turns out that Wint used to work at Savopoulos' company, American Iron Works, but it is not clear whether Wint had been fired.

On Thursday, federal marshals tracked the ex-con to a Howard Johnson Express Inn at College Park, Maryland. They said that Wint was in a white Chevrolet Cruze while traveling to D.C. with two women.

Their vehicle was following a white box truck, which police believe was driven by Wint's brother, reports The New York Daily News. Another man was also inside the truck.

All of the people with Wint were taken into custody. However, they have been questioned and released.
