Police have charged a man with second-degree murder in connection with the deaths of a mother and her son at a home in Evanston on Thursday afternoon.

Guevara Wilson Clorina, 26, from Calgary has been charged with two counts of second-degree murder in connection to the deaths of Chona Manzano, 35, and her son Gabriel, 5.

Police were called to a home in the 200 block of Evanspark Circle N.W. at about 12:50 p.m. on Thursday after they received a 911 call from a neighbour.

Manzano and her son were found deceased at the scene.

"There was a family member who attended the residence in response to a report of a problem. Upon attending the residence, he entered and he found the female victim on the main floor and the child victim on the second floor, both deceased. He then exited the residence, alerted a neighbour, who called 911," said CPS S/Sgt. Doug Andrus.

Autopsies were completed late Friday and police confirm that both died as a result of a stabbing.

Calgary police circulated details of a vehicle that they believed to be connected to the residence to nearby policing agencies.

RCMP found the vehicle in a ditch next to a rural road north of Olds and a suspect was taken into custody.

Clorina was picked up on Thursday afternoon and taken into custody without incident.

Police say he is related to the deceased.

“The suspect is believed to be related to the deceased but he is not an immediate family member and did not reside at the same residence,” said CPS S/Sgt. Doug Andrus.

Police say there are two other children in the family who were not at home at the time of the incident and that they acted quickly to ensure their safety.

"Our Child at Risk Response Team and the multi-agency school support team, along with Child and Family Services were involved with the family. They were brought to the Westwinds building and offered those services," said Andrus.

Andrus says that the father was not at home and is understandably upset.

"Very distraught. Of course, he's just lost his wife and a child. He is grateful for our investigation and that we've brought it to a conclusion so quickly, but again it doesn't replace the loss of a partner and a child," said Andrus.

Investigators are processing a number of scenes in the home and have recovered a Knife at the scene.

Police say they have not attended the residence in the past and that they are not looking at any other suspects in the investigation.

Clorina will appear in court on May 21.
