The reward for information about the murder of a 19-year-old in Arlington has been increased to $6,000.
Evan Lacey had been missing for more than two weeks before his body was found on Jan. 4.
Lacey's family last saw him on the morning of Dec. 17 as he left their Arlington home for work in Grand Prairie.
He was reported missing two days later, and on Dec. 21 his vehicle was found in the 4900 block of S. Hughes Avenue in Fort Worth, police said.
Lacey's body was discovered in a wooded area in the 7100 block of Webb Ferrell Road South, hours after Lacey's family held a search for him in Fort Worth.
Police said they thought foul play was involved in Lacey's disappearance and death because of evidence found in his car.
But weeks later, they said they had no viable leads.
The latest news from around North Texas.
Lacey's father, Van Lacey, said the family strongly believed someone knows something they aren't sharing.
“He knew so many people, touched so many people’s lives, that I wouldn’t have imagined that we’ve gone a month now, over a month, and no one has spoken up," Van Lacey said.
According to a flyer posted by Lacey's aunt, Tailar Lacey, a reward of up to $6,000 will be given for any information that leads to the conviction of those responsible for Lacey's murder.
“Just please speak up. I’m begging for someone to speak up with information regarding who has done this to our son," Van Lacey said.
Those with information about the case should contact Det. Coleman at 817-459-5373 or call Crime Stoppers of Tarrant County at 817-469-8477.
According to Lacey's post, a flyer distribution is scheduled for Saturday, Feb. 15 in Arlington.
