A dad is to stand trial accused of murdering his two-month-old son at a house in Ayrshire.
Brian Penn, 30, allegedly killed Kaleb Penn in Ayr on November 1, 2017, after ‘shaking and compressing’ the child.
Little Kaleb died a couple of days later at Glasgow's Royal Hospital for Children.
Prosecutors claim Penn did "repeatedly inflict blunt force trauma" on the child by "means unknown".
Penn, of Mossblown, Ayrshire, faces a separate charge of earlier attempting to murder the baby at the same house between October 13 and 31, 2017.
Penn again had his attendance excused during a short hearing at the High Court in Glasgow on Wednesday.
His QC Brian McConnachie had previously denied the charges on his behalf and lodged a special defence of incrimination.
Both the advocate and prosecutor Erin Campbell agreed a trial could be fixed.
Lady Stacey asked Mr McConnachie if the case will mainly focus on "medical" evidence.
The QC told her: "Pretty much, yes."
The judge set a trial due to begin in May. The case could last up to seven days.
Bail for Penn was continued meantime.
