A Texas man has been arrested on a first-degree murder charge after police say he repeatedly shot his 27-year-old son, and then stabbed him to death after delivering a 20-minute lecture.

Sherman Shirley Fricks, 69, of Deer Park, was arrested on Sunday morning for the slaying of his son, Sherman Palmer Fricks, in what police have labelled an unprovoked attack.

Police were called to the family's home in the 1300 block of Meadowlark Street at around 11am and found Sherman Palmer suffering from multiple gunshot and stab wounds.

Prosecutors said the father and son (pictured together) had a tense relationship, and the died had grown tired of the 27-year-old's attitude

The 27-year-old man was rushed to Bayshore Hospital, where he was pronounced dead from his injuries.

During a probable cause hearing held on Monday, prosecutors said that the relationship between the father and son had been strained for some time, and that the elder Fricks had grown tired of his son's attitude, reported Houston Chronicle.

‘[Fricks] stated that he had called law enforcement on [his son] in the past, but they were never able to fix it,’ a prosecutor said. ‘So today, he decided to fix it.’

On Saturday, Sherman Palmer had broken his phone, so his father drove him to a store to have the device repaired. On the way home, the son began kicking the back of the front passenger seat that was occupied at the time by his father's girlfriend, according to a police interview with the dad.

The following morning, the father allegedly grabbed a .380 pistol and waited for his son to return from lunch.

Fricks told police his initial plan was to shoot his son in the back.

Prosecutors said in court that when Sherman Palmer entered the house, his father asked him what he had eaten.

The son responded with a 'smart remark' and turned to face him, at which point the father opened fire on him, according to the court documents.

‘[Fricks] just started shooting him until nothing else came out of the handgun. After the shooting, [his son] was still alive,’ the papers read.

As the son lay dying on the floor, the dad allegedly launched into a 20-minute lecture before grabbing a kitchen knife

As Sherman Palmer lay dying on the floor, it is alleged that his father launched into a 20-minute 'father-son' talk.

At the end of the lecture, prosecutors said the father took a kitchen knife and stabbed his son multiple times, including in the chest.

A judge set the father's bond at $60,000, which he later posted and was released.
