Travis Fox was arrested on Thursday, March 14 on two counts of murder.
A judge denied him bond on Friday, so Fox now remains in the Washington County Jail.
According to a probable cause report, the 2011 death of Fox's 6-month-old son in West Fork was ruled suspicious and Fox remained a person of interest.
On Wednesday, March 13, 2013, Springdale police responded to a report of a 7-month old deceased infant at Northwest Medical Center in Springdale, which was also ruled suspicious.
Fox was arrested Thursday after being questioned by police.
His next court date is set for April 17.
