ST. LOUIS – Authorities have now identified a suspect killed in a shootout with a St. Louis officer and an ATF special agent last week, along with three homicide victims linked to the investigation.

On Wednesday, five days after the incident, the St. Louis Metropolitan Police Department identified the suspect as James Carter, 61, of St. Louis.

St. Louis police also identified three presumed homicide victims connected to Carter as Tyrone Mason, 57, of St. Louis; Ariel Eastling, 34, of St. Louis; and James Rodriguez, 58, of Kinloch, Missouri.

On Friday, May 9, police initially responded to a ShotSpotter alert from a a home in the 5100 block of Wells Avenue. One homicide victim was found dead outside the home earlier in the morning.

Police say Carter came out of the home and spoke with officers briefly, then went back into the home to retrieve a weapon and fire shots. Carter was fatally shot in a gunfire exchange involving one St. Louis officer and one ATF agent.

After the shootout, the armed suspect and two additional homicide victims were found deceased in that home.

Police did not disclose which two of the three victims were found in the home, though previously reported that one man was found dead outside, while one woman and another man were found inside the home.

The events all began around 4:20 a.m., when St. Louis police responded to a ShotSpotter alert outside the home on Wells Avenue. As officers arrived to the scene, they found one man deceased near a front porch.

St. Louis police then requested the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to help with the investigation, specifically obtaining a search warrant to collect evidence.

Then, around 7 a.m., a man, later identified as Carter, left from inside the home in question and engaged in a brief conversation with officers. Carter then went back inside the home, and reappeared armed with a gun. Police say Carter then began firing shots, leading to an exchange of gunfire.

When SWAT teams arrived inside the home, they found Carter dead near the entry of the home. After that, a woman was found dead in the living room and a man was found dead in the basement of that home.

As of Wednesday, police have not disclosed a motive of the nature of Carter’s connection to the three victims.
