Background

A lieutenant (promoted from inspector) in the San Francisco Police Department, he was once the partner of inspector Andy Trudeau. Darryl has a wife named Sheila and two sons; Darryl Jr. and Michael . His father's name is Luther Morris.

Darryl followed in his father's footsteps by pursuing a career in police enforcement. At first Darryl is suspicious of the Halliwell sisters' recurring connection to mysterious murders and crimes but he soon learns (after the death of Andy) that the Halliwells' are merely a force of good witches trying to bring justice and protection to the world. Since finding out the sisters' secret, he has been of great help to them by covering up unsolved cases related to demonic activity, granting them favours and giving them general support, even if it was just by visiting Piper after Leo had become an elder. However, when he is nearly killed, by the Cleaners covering up for The Charmed One's magic, he falls out with them over the risks he takes. Although after, he still continues to do them favours, and never blows their secret. His connection with the sisters is proven when at the end of the seventh season finale, he sees three women, the look on his face and his expression suggests that he knows that the sisters had survived the terrible battle somehow. This is his last appearance on charmed, as Darryl's wife Sheila forces him to move to another state in order to start a fresh. 

At one time, Phoebe and Paige took his soul, albeit unwillingly, in order to get Leo out of Valhalla. Although initially he did not agree, once they had his soul he helped Leo as much as he could, proving his loyalty. Sadly shortly after they escaped, more warriors from Valhalla came accidentally with them, which lead into him being attacked. He was later healed by Leo. Later on in the season, after the incident with his death penalty, he did not cover up for Chris, when stealing a car to chase an evil version of Mr Right. In season seven, he does not help the sisters, and contact with them isn't as regular as it used to be. He works with Inspector Sheridan, who knows that the sisters are hiding something. He didn't help the sisters, but at the same time, he did not reveal their secret.

As of Season 8, Darryl is transferred to the East Coast, where contact with the sisters is non-regular and not on screen.
