DARROW — Ascension Parish sheriff’s detectives using new information from a key witness arrested two men Friday suspected of killing a 19-year-old man June 27 in Darrow’s Astroland subdivision, deputies said.

Detectives arrested Brian Russell, 29, 39015 Neptune St., Darrow, and Tevis Harvey, 22, 5053 Galaxy Blvd., Darrow, and booked both of them on counts of second-degree murder, deputies said in a news release Friday.

Russell and Harvey were to be booked into Ascension Parish Prison in Donaldsonville late Friday, deputies said.

Darin Keith Smylie Jr., 19, 39068 Venus St., Darrow, was found shot dead in his home by his father after the elder Smylie returned from work about 5 p.m. June 27, deputies have said. Darin Smylie, a longshoreman, had the day off.

The Smylies lived in the Astroland neighborhood surrounded by immediate and extended family members, and Darin Smylie’s slaying rocked the Darrow community along the east bank of the Mississippi River.

Detectives worked for several weeks to develop leads and asked for the public’s aid in finding the killer or killers.

Russell’s and Harvey’s listed addresses are in Astroland subdivision, maps show.

Sheriff’s Maj. Benny DeLaune said the witness who came forward Friday had provided key details that led to arrest warrants being issued within hours.

DeLaune said that Russell and Harvey already had been the focus of the investigation for the past two weeks and that detectives previously found multiple individuals who put them near the scene of the crime.

But he said detectives didn’t have enough to seek arrest warrants for the pair until the key witness came forward.

DeLaune said detectives believe they determined a motive for the shooting but he declined to disclose it at this time.

DeLaune said neither Russell nor Harvey owns a white pickup truck that the detectives had previously said was seen in the vicinity around the time of Smylie’s death.

Detectives suspected earlier in the investigation that the pickup was somehow connected to the slaying.

DeLaune said detectives have not determined who owns the truck, but said it is looking less and less likely that the truck is actually connected to the slaying.
